Our original opinion in this appeal, reported at
In the central issue in this appeal, Charles D. Pace invites us to hold that which the Supreme Court has rejected in a factually indistinguishable case — that a barn physically separate from a home enjoys Fourth Amendment protection because it is within the curtilage of the home, and that the area surrounding a barn is protected as a “business curtilage.” Because we do not believe that the Supreme Court would treat this case any differently than it did
United States v. Dunn,
I.
In October 1988, law enforcement officials in Travis County, Texas received information that marijuana was being grown in large quantities in a barn located on a 43-acre tract at the end of Lambert Road in Travis County. The barn was owned by Robert and Ouida Pace, the parents of appellant Charles Pace. In May 1989, a different informant contacted officials and told them that a large-scale marijuana operation was being conducted in the barn. Periodic surveillance was established on the barn and the property, and police observed appellant Pace, as well as John K. Treanor and John D. O’Brien, on the property.
On June 12, 1989, two officers entered the property and, looking through a hole in the barn, observed marijuana plants growing inside. On the basis of this information, a search warrant was issued for the barn. On June 15, agents of a joint task force composed of DEA agents and the Organized Crime Unit of the Austin Police Department executed the warrant. The officers seized 796 growing marijuana plants and a prescription bottle in Pace’s name with marijuana seeds inside, and arrested Pace, O’Brien and Treanor. Searches of the defendants’ persons yielded keys to the padlock securing the entrance gate to the property and a key to a safe deposit box at a bank in Austin. On the basis of the information obtained from the search of the barn and the arrests, warrants were issued for the residence of Pace, the residence O’Brien shared with Treanor and the safe deposit box. At the O’Brien and Trea-nor residence officers seized documents, photographs, ledgers, catalogs, accounts, receipts, magazines, a, small amount of marijuana and $5,665 in cash; at the Pace residence they seized a triple beam balance scale, a small quantity of marijuana and various business and phone records; and from the safe deposit box they seized a key to the gate of the property where the barn was located.
All three defendants were indicted for conspiracy to possess with intent to distribute more than 100 marijuana plants in violation of 21 U.S.C. §§ 841(a)(1) and 846, and knowingly possessing more than 100 marijuana plants with intent to distribute in violation of 21 U.S.C. § 841(a)(1). 1 Each *273 filed a motion to suppress the evidence seized from the barn on June 15, arguing that the officers’ observations of June 12, which formed the basis for the affidavit in support of the search warrant, resulted from an unconstitutional search of the barn. They further argued that the warrants for the searches of their homes and the safe deposit box were tainted by the unconstitutional search of the barn and that the evidence seized at those locations constituted “fruit of the poisonous tree.”
After holding a hearing on the suppression motion, the district court made detailed findings of fact concerning the barn, the surrounding property, and the June 12 search. At the time of the search, the property was being used in part for the purpose of farming and ranching. The entrance to the property is secured by a closed gate with a lock and chain and a “Beware of Dog” sign. The property is surrounded by a fence, and there are numerous interior fences. The fences are constructed of “hog wire” topped with several strands of barbed wire. The fences are approximately four feet high and are designed to block the passage of objects larger than four to six inches in diameter.
The property is improved with a small wood frame house and storage shed located within 100 feet of the front gate. Behind a garage, approximately 50-60 feet from the house, is the barn and stock pen. The barn is separated from the rest of the house by an interior fence. The barn, a commercial structure used for the business of farming and ranching, is constructed primarily of corrugated steel panels and is completely enclosed. It has no windows, and the only access is through two locked doors. Police helicopter surveillance of the property revealed that the barn was covered with translucent corrugated sheeting of the type used in greenhouses, but was not so transparent that the police could see through it. The interior of the barn was not visible from outside the property.
On June 12, two officers entered the property, one by squeezing through a gap between the main gate and a fence post and the other by climbing over the gate. After knocking on the door of the house and looking through a window, the officers determined that the house was vacant. They crossed at least two more gates and went to the back side of the barn, where they found a small opening. The officers could not see inside the barn from any distance, but had to press their faces close to the opening to see inside. Their observation of marijuana plants in the barn led them to apply for a search warrant, which they executed on June 15.
On the basis of these facts, the district court denied the suppression motion. The court first found that, because the barn was in an open field outside the curtilage of the home, the defendants had no reasonable expectation of privacy which would require the application of Fourth Amendment principles. The court determined that the barn was outside the curtilage by applying the four-part analysis of
United States v. Dunn,
Pace proceeded to trial and was convicted by a jury on both counts. The district judge sentenced Pace to concurrent terms of imprisonment of 51 months for the drug convictions. He added to this a consecutive prison term of nine months, pursuant to 18 U.S.C. § 3147, because following his arrest and pretrial release Pace was convicted of misdemeanor assault in state court. Pace also received a five year period of supervised release, a fine of $10,000, and a $100 special assessment. Pace appeals the denial of his suppression motion, and the government appeals the sentence.
II.
A. The Search of the Bam
Pace first argues that the warrant-less search of the barn was unconstitutional because it took place within the curtilage of the home. We find this argument foreclosed by the Supreme Court’s decision in
United States v. Dunn,
Two law enforcement officials made a warrantless entry by crossing the perimeter fence and one interior fence. Standing midway between the residence and the barn, one official smelled what he thought was a chemical involved in the manufacture of phenylacetone coming from the direction of the barns. The officers crossed a barbed wire fence and looked into the smaller of the barns, where they found only empty boxes. They then crossed another barbed wire fence and the wooden fence encircling the front of the larger barn, walked to the locked gates, and viewed the interior of the barn by shining a flashlight through the netting. The officers did not enter the barn, but obtained a warrant authorizing a search of the ranch.
The primary question before the Court was whether the barn was within the protected curtilage of the house. The Court began by referring to its recent decision in
Oliver v. United States,
The extent of the curtilage to which Fourth Amendment protection attaches is not unlimited. In
Dunn,
the Court undertook to define with more precision than it had previously the boundaries of this space. The inquiry is guided by “factors that bear upon whether an individual reasonably may expect that the area in question should be treated as the home itself,”
Applying the factors to the facts in
Dunn
itself, the Court found that the barn lay outside the protected curtilage in open fields. First, the barn was 50 yards from the fence surrounding the house and 60 yards from the house. This substantial distance alone “support[ed] no inference that the barn should be treated as an adjunct of the house.”
Id.
at 302,
As the district court held, analysis of these factors in the instant case yields the same result as in Dunn. Apart from the need for the officers in this case to press their faces up to the barn, the factual similarity to Dunn is striking. The barn was located a significant distance from the house; it was separated from the house by an interior fence; earlier surveillance, including aerial photographs indicated that it was pot being used for activities associated with the intimacies of home life; 6 and it was readily visible from the surrounding area. Pace attempts to distinguish Dunn by pointing out that the officers in this case could not see into the barn except by putting their faces up to the siding. He argues that this is somehow different than standing outside a barn and shining a flashlight on a netting. However, the holding of Dunn was that once the officers were standing in open fields outside the protected curtilage of the home, they were privileged to view the inside of the barn. The officers in this case were likewise privileged 7 to stand in the open field, and the distance between their bodies and the structure into which they peered is of no consequence. To hold otherwise would re *276 quire us to draw a specious distinction between those open field searches in which officers physically come up against a structure and those in which they are able to see inside even while standing back from the structure. The officers in this case did not physically tamper with or enter the barn in order to view its contents, but merely stood outside in the open field and looked in. 8 Thus, the search did not violate the Fourth Amendment’s proscription of searches within the curtilage of the home.
Relying on
Dow Chemical v. United States,
In
Dow Chemical,
the Court reaffirmed that there is an expectation of privacy in commercial structures which society is prepared to accept as reasonable, thus bringing the interiors of such structures within the protections of the Fourth Amendment.
B. The Search of the Residence
The information the police obtained from the search of the barn and the arrests of Pace, O'Brien and Treanor led them to file affidavits in support of warrants to search the suspects’ residences. Pace contends that even if the information provided in these affidavits was true, the warrant for the search of his home was still unsupported by probable cause. He characterizes the officers’ contention in the affidavit that drug dealers normally keep records at their homes as too conclusory to constitute probable cause. Certainly, under
United States v. Freeman,
While the evidence provided in the affidavit in
Freeman
connecting the defendant’s activities to his home was too tenuous to support a finding of probable cause to search for records and drug paraphernalia, that case does not, as Pace seems to suggest, categorically
prohibit
police officers from searching a suspect’s home when the suspect has been arrested at another location. We concluded that there
was
probable cause to search for passports, personal identification papers and bank and safety deposit box records because these were “precisely the sorts of items which people tend to keep at home among their personal papers and effects.”
Id.
at 949. Similarly, in
United States v. Maestas,
The circumstances surrounding the search of Pace’s residence are identical in all important respects to the search we upheld in
United States v. Raborn,
III.
We turn next to the government’s appeal of Pace’s sentence. Pace was convicted of possession with intent to distribute more than 100 marijuana plants and conspiracy to possess with intent to distribute more than 100 marijuana plants, in violation of 21 U.S.C. §§ 841(a)(1) and 846. These crimes are punishable under 21 U.S.C. § 841(b), which provides that in the case of a violation of § 841(a) involving more than 100 marijuana plants, the sentence shall be “a term of imprisonment which may not be less than 5 years and not more than 40 years.”
In the presentence report, the probation officer noted the statutory minimum but computed Pace’s Sentencing Guideline range at 51 to 68 months imprisonment. 10 The district court sentenced Pace to 51 months imprisonment on each count to run concurrently, nine months less than the statutory minimum, and then added nine months pursuant to 18 U.S.C. § 3147 because Pace was found guilty of assault in state court following pretrial release. In response to the government’s request for an explanation at the sentencing hearing of why he was going below the statutory minimum, the judge explained that “I was intentionally going below that in this case only because of Title 18, United States Code, Section 3147, through which I brought the sentence up to a total equal to the statutory minimum.”
This method of computing the sentence was incorrect. First, the district judge should have started with the statutory minimum sentence of 60 months. We have repeatedly held that the Guidelines do not supplant the minimum sentences provided for in various criminal statutes.
United States v. Garcia-Pillado,
Second, the judge should not have enhanced Pace’s sentence under 18 U.S.C. § 3147. That section, as amended, provides:
A person convicted of an offense committed while released under this chapter shall be sentenced, in addition to the sentence prescribed for the offense to—
(1) a term of imprisonment of not more than ten years if the offense is a felony; or
(2) a term of imprisonment of not more than one year if the offense is a misdemeanor.
A term of imprisonment imposed under this section shall be consecutive to any other sentence of imprisonment.
This statute provides for an enhanced sentence for a person who commits a federal crime while on release, and the enhancement applies to the sentence for the new crime committed while on release, not the original crime for which the defendant is *279 on release. 12
Despite these two errors, we see no reason to disturb Pace’s sentence. The end result was a sentence of 60 months, the mandatory minimum for Pace’s offense. The judge’s statements about why he was going below the minimum and then adding nine months for the enhancement indicate that he wanted to give Pace the statutory minimum. Were we to remand, Pace would be subject only to the possibility of receiving three more months (63 months was the upper range of his Guideline sentence). In light of the judge’s apparent intent to give Pace only the 60-month minimum, we consider the errors harmless and see no reason to disturb the sentence. 13
IV.
For the foregoing reasons, we AFFIRM Pace’s conviction and sentence.
Notes
. Although all three defendants were charged jointly, we treat their appeals in separate opinions.
See United States v. Treanor,
.
Dunn
requires, for the purpose of determining whether a particular search took place within the curtilage, an analysis of (1) the proximity of the area claimed to be curtilage to the home; (2) whether the area is included within an enclosure surrounding the home; (3) the nature of the uses to which the area is put; and (4) the steps taken by the resident to protect the area from observation by people passing by.

. The Fourth Amendment "indicates with some precision the places and things encompassed by its protections ... '[T]he special protection accorded by the Fourth Amendment to the people in their "persons, houses, papers, and effects," is not extended to the open fields. The distinction between the latter and the house is as old as the common law.’ ”

Oliver,
. The officers' method of observing the contents of the barn in this case arguably was less intrusive than in Dunn, as they merely looked into the barn with the naked eye. In Dunn, the officers used a flashlight as an aid.
. Our holding disposes of Pace’s contention that the statements he made after the search of the barn and his arrest were inadmissible at trial.
. Based on the amount of marijuana involved, the probation officer set the base offense level at 22 and added two points for obstruction of justice, bringing the total offense level to 24. Pace had a criminal history score of zero, resulting in a sentencing range of 51 to 63 months imprisonment. See U.S.S.G. Sentencing Table.
.All circuits which have reached the issue are in accord with this basic principle.
See United States v. Rodriguez,
. We overlooked this in our original opinion, holding that the nine months the judge gave Pace for the state court misdemeanor had to be added to the statutory minimum for the federal drug offense. On our own motion, we asked the parties to file letter briefs addressing the applicability of 18 U.S.C. § 3147 to state offenses committed while on release for a federal offense. Both parties agree that § 3147 has no applicability in these circumstances.
. In its letter brief, the government suggests that we vacate and remand because the probation officer improperly placed Pace in criminal history category I. The government contends that, under U.S.S.G. § 4A1.1(b), the officer should have added two points to Pace’s criminal history score for the state assault conviction, thus placing him in criminal history category II. With an adjusted offense level of 24 and a criminal history category of II, Pace’s Guideline range would be 57 to 71 months imprisonment. The government implies that we should remand to enable the district judge to impose a sentence of at least 60 months but potentially reaching 71 months. As the government never contested the calculation of Pace’s criminal history category in its brief on appeal, we do not consider it here.
