OPINION
In the course of his duties, a Minnesota conservation officer entered the fish house of Marvin Russell Larsen (respondent) to conduct a routine license check. Upon entry, the officer discovered that respondent had three fishing lines in the water and that he was in possession of marijuana. Respondent was charged with a controlled substance offense and angling with one more line than allowed under his license. Respondent moved to suppress all evidence as obtained in an unauthorized search of his fish house. The district court granted respondent’s motion and dismissed all charges, and the court of appeals affirmed. We affirm.
*146 On the evening of January 31, 2001, Officer Scott Fritz, a licensed peace officer employed by the Minnesota Department of Natural Resources as a conservation officer, was patrolling fish house activities on Circle Lake in Rice County, Minnesota. Circle Lake has a public access that provides an entrance point for anglers and snowmobilers and Officer Fritz estimated that on this particular day there were approximately 60 to 80 fish houses on the lake. In the performance of his duties under Minn.Stat. § 97A.215 (2000), 1 Officer Fritz proceeded from fish house to fish house knocking on occupied shelters, identifying himself, and checking licenses. At approximately 6:30 p.m., Officer Fritz arrived at respondent’s fish house which was illuminated and had a vehicle parked next to it. Officer Fritz knocked on the door, identified himself as a state game warden and simultaneously opened the door. As he entered, he had no reason to suspect a violation of fishing laws and concedes that respondent did not expressly consent to his entry. Officer Fritz believed however, that he had authority to enter and inspect occupied fish shelters in this manner under Minnesota law.
Upon entering the fish house, Officer Fritz noticed a strong smell of marijuana and saw what appeared to be a marijuana cigarette. He conducted a pat-down search of respondent and found a bag of marijuana. He also noticed that respondent had three lines in the water when only two are permitted. Respondent was charged with possession of a controlled substance pursuant to MinmStat. § 152.027, subd. 4 (2000), and unlawful angling lines pursuant to Minn.Stat. § 97C.315 (2000).
Respondent moved to suppress all evidence obtained as a result of Officer Fritz’s entry and search of his fish house and to have the charges against him dismissed, asserting that Minn.Stat. § 97A. 215 authorizing a conservation officer to “enter and inspect” his fish house was unconstitutional. Respondent further argued that a fish house is a temporary place of occupancy for anglers, and as such, it is frequently equipped with various accommodations for short-term living including heating, cooking, and other conveniences such as television and sleeping accommodations, much like a private home, and as with a private home, an enforcement officer is without lawful authority to conduct a search of a private fish house without a warrant or other circumstance authorizing an entry. The district court granted respondent’s motion ruling that although a fish house was not necessarily comparable to a home, an occupant has a reasonable expectation of privacy and Officer Fritz’s entry into respondent’s fish house without consent, a warrant, probable cause, or ar-ticulable suspicion was unlawful. In doing so, the district court rejected the state’s argument that the exception to the warrant requirement for administrative inspections of “closely regulated” businesses applied,
see New York v. Burger,
The state appealed asserting that Officer Fritz’s entry into respondent’s fish *147 house without a warrant was authorized under Minn.Stat. § 97A.215, subd. 3:
An enforcement officer may, at reasonable times:
(1) enter and inspect the premises of an activity requiring a license under the game and fish laws;
‡ ⅜ ⅜ ⅜?
The state argued that the statute and regulatory inspections conducted pursuant to it are constitutional and that despite whatever comforts may be added, occupants of a fish house have no greater an expectation of privacy than occupants of a commercial business. The court of appeals disagreed and affirmed the district court’s ruling.
State v. Larsen,
I.
In reviewing pretrial orders suppressing evidence where the facts are not in dispute, we independently review the record and determine, as a matter of law, whether the district court erred in suppressing the evidence.
See State v. Harris,
The right to be free from unauthorized entry into one’s abode is ancient and venerable. As William Pitt, Earl of Chatham, so vividly put it in 1766:
The poorest man may in his cottage bid defiance to all the forces of the Crown. It may be frail, its roof may shake; the wind may blow through it; the storm may enter, the rain may enter — but the King of England cannot enter; all his force dares not cross the threshold of the ruined tenement!

Olmstead v. United States,
[T]he right to be left alone — the most comprehensive of rights and the right most valued by civilized men. To protect that right, every unjustifiable intrusion by the government upon the privacy of the individual, whatever the means employed, must be deemed a violation of the Fourth Amendment.

Entry constitutes a search whenever there is an intrusion upon an area where a person has a reasonable expectation of privacy.
State v. Hardy,
The Supreme Court has recognized that an expectation of privacy is reasonable in one’s home and curtilage,
Payton v. New York,
The Supreme Court and the courts of Minnesota have applied balancing tests to determine the constitutionality of law enforcement searches and seizures under the federal and state constitutions where the nature and significance of the intrusion on the individual’s privacy interests are balanced against the gravity of the public concerns it serves and the degree to which the conduct at issue advances the public interest. For example, in
Prouse,
the Supreme Court held that the state’s interest in ensuring roadway safety did not outweigh the intrusion on the privacy and security of persons detained in random
*149
automotive stops for the purpose of checking driver’s license and registration,
We applied a balancing test in
Ascher
v...
Comm’r of Public Safety,
The state argues that longstanding laws regulating angling in Minnesota have alerted anglers for decades that conservation officers are authorized to enter their fish houses without permission or probable cause, citing Minn.Stat. § 97.50, subd. 1(4) (1945) (now found at Minn.Stat. § 97A.215, subd. 3), and further, anglers are aware that they are prohibited from locking out regulatory inspectors, citing Minn.Stat. § 97C.355, subd. 3 (2000). Therefore, the state argues, anglers in a fish house can have no reasonable expectation of privacy.
We consider the nature of the premises here — á fish house, erected and equipped to protect its' occupants from the elements and often providing eating, sleeping, and other facilities — as providing privacy for activities “ ‘recognized and permitted by society.’ ”
Carter,
*150
Our ruling in
Ascher
is particularly informative here. In
Ascher,
we ruled that the key issue was not whether the stops were discriminatory, but that the state had failed to articulate a sufficiently persuasive reason for departing from the general requirement that stops of motorists be based on individualized suspicion.
Comparing the privacy interest of appellant in his fish house with that of the occupants of motor vehicles stopped at the roadblocks in
Ascher,
we have no difficulty concluding that appellant’s privacy interest is at least as great as that of the motor vehicle occupants in
Ascher.
Personal activities of occupants of a fish house would certainly have privacy values “ ‘recognized and permitted by society,’ ”
Carter,
II.
The state argues however, that based on the duration and pervasiveness of Minnesota’s regulatory scheme of conservation evidenced by our constitution and state laws,
6
entry into fish houses falls within an exception to the constitutional protections from search because it is an administrative inspection in a “closely regulated” industry.
See, e.g., United States v. Biswell,
*151
In
Burger,
the Supreme Court considered the constitutionality of a New York statute authorizing warrantless inspections of automobile junkyards.
(1) There [is] a “substantial” government interest that informs the regulatory scheme pursuant to which the inspection is made;
(2) The warrantless inspections [are] necessary to further the regulatory scheme; and
(3) The statute’s inspection program, in terms of certainty and regularity of its application, [provides] a constitutionally adequate substitute for a warrant.
id at 702-03,
The state claims that all three criteria are met justifying Officer Fritz’s warrant-less search on the basis that fishing is a regulated industry. The state first argues that it clearly has a substantial interest in regulating the taking of its fish to ensure the resource is not exploited or depleted, and that the regulatory scheme at issue here informs this substantial interest because the state’s interest in resource conservation outweighs the privacy interests of the angler. The state claims that this enforcement scheme is necessarily different from that used to enforce traffic regulations because automobile travel is “basic, pervasive, and often necessary,” citing
Prouse,
Second, the state argues that warrant-less inspections are necessary to further Minnesota’s regulatory scheme because the possibility of being randomly checked by a conservation officer is essential for deterring violations and protecting Minnesota wildlife. 8 As to the third requirement in Burger, the state asserts that its inspection program provides a constitutionally adequate substitute for a warrant because *152 Minnesota statutes provide anglers with clear notice that random unannounced inspections will be conducted.
Respondent claims that these criteria are not met, but that even if they are, the exception to the warrant requirement articulated in
Burger
is limited to commercial activities and has no application to recreational ice fishing.
9
The state responds that it is reasonable under
Carter
to extend the
Burger
analysis to Minnesota fish houses because in
Carter,
the Supreme Court held that a short-term guest in another’s home engaging in a commercial activity did not have a legitimate expectation of privacy to challenge a search of the home.
Relying on Carter, the state asserts that the applicability of Burger to fish houses cannot be dismissed merely by concluding that a fish house is not a place of business. The activity in which the occupants are engaged is also important and affects an individual’s expectation of privacy. The state argues that the taking of fish is more like a closely regulated business than a domiciliary activity because it constitutes a property transaction between the state, as owner of the fish, and the angler who has actively chosen to participate and acquiesce in the regulatory scheme by obtaining a permit to fish in a fish house. 10 The conservation officer, then, is uniquely empowered to enforce these regulations not as an agent of the state’s sovereign police power, but as a “warden” of the state’s fish and game.
Respondent argues the state’s reliance on
Carter
is misplaced, characterizing
Carter
as a case about standing, and rejects the state’s argument that ice fishing is sufficiently similar to a “closely regulated” industry to justify a warrantless search. A more fitting analogy, respondent asserts, would be an unauthorized entry into a home, or perhaps a motor home, as many fish houses are equipped with similar amenities, and even if a fish house could be characterized as commercial property, the occupant still maintains at least some expectation of privacy, citing
Katz,
We do not perceive recreational ice fishing in a private fish house comparable to running an automobile junkyard business,
*153
operating a licensed gun dealership, or engaging in the sale of alcoholic beverages for purposes of the closely regulated industry exception.
See Burger,
As the Supreme Court noted in
Almeida-Sanehez v. United States,
A central difference between [Colonnade and Biswell ] and this [case] is that businessmen engaged in such federally licensed and regulated enterprises accept the burdens as well as the benefits of their trade, whereas the petitioner here was not engaged in any regulated or licensed business.
(emphasis added.) We conclude that angling from a fish house is not a closely regulated industry fitting within the exception to the need for constitutional authorization for a search as set forth in Burger.
While the state clearly has a strong interest in regulating and protecting its wildlife, by no means does that interest exceed the state’s interest in saving human lives by deterring drunk driving on our roads found insufficient to outweigh the privacy interests of the occupant of a motor vehicle in
Ascher.
Affirmed.
Notes
. Minnesota Statutes § 97A.215, subd. 3 (2000) provides:
An enforcement officer may, at reasonable times:
(1) enter and inspect the premises of an activity requiring a license under the game and fish laws; and
(2) stop and inspect a motor vehicle requiring a license under the game and fish laws.
. The court of appeals emphasized the similarity between the facts of this case and those of
State v. Krenz,
. The statute does not define the "at reasonable times" limitation it places on an enforcement officer’s authority to inspect under subdivision 3. In comparison, the language of subdivisions 1 and 2, pertaining to the storage of wild animals and the inspection of certain records respectively, does not reference reasonableness but does limit an enforcement officer's right to inspect to circumstances where the officer "has probable cause to believe” there has been a violation. Minn.Stat. § 97A.215, subds. 1-2 (2000).
. The legislature apparently does not disagree because in Minn.Stat. § .97A.205 (2000), outlining the powers of enforcement officers including conservation officers, it has provided: “Nothing in this section grants an enforcement officer any greater powers than other licensed peace officers.'' See
also Sorenson,
. It is true that unlike traffic violations, fishing violations committed in fish houses may be difficult to detect and evidence may be destroyed before a warrant can be obtained, but ease in enforcing the law has never been a sufficient justification for government intrusion. As we stated in
Hardy,
where we ruled that a police officer's request that a defendant open his mouth was a search for Fourth Amendment purposes: "[T]he possibility that [the defendant] might ingest whatever substance was in his mouth did not eliminate the need for police to have probable cause to believe that the substance was evidence of a crime before they could search for it.”
. See Minn. Const, art. XIII, § 12 (imposing on the state a duty to manage "[h]unting and fishing and the taking of game and fish * * ⅜ by law and regulation for the public good” as they are "a valued part of our heritage”); see generally Minn.Stat. 97A, 97C (2000).
. The state further emphasizes these points by citing language from Justice Blackmun’s concurrence in Prouse where he distinguished the state’s interest in police spot-checks for motor vehicles from those at stake in the context of hunting and fishing:
I would not regard the present case as a precedent that throws any constitutional shadow upon the necessarily somewhat individualized and perhaps largely random examinations by game wardens in the performance of their duties. In a situation of that type, it seems to me, the Court's balancing process, and the value factors under consideration, would be quite different.
. Amicus Minnesota Conservation Officers’ Association (MCOA) joins in these arguments, adding that if a fish house is treated as a home for Fourth Amendment purposes it would render enforcement of the numerous resource preservation regulations impossible, or at least ineffective, as evidence could immediately be disposed of when the conservation officer requests permission to enter and a fish house could be moved before a warrant could be secured, if a warrant could be secured at all.
. Respondent emphasizes this point by distinguishing the activity at issue here from "commercial fishing," defined under state law as "taking fish * ⅜ * for sale.” Minn.Stat. § 97A.015, subd. 9 (2000).
. The state asserts an angler is no different than a gun dealer who, by choosing to accept a federal license and engage in the business of dealing in guns, essentially consents to the various inspections authorized by law, citing
United States v. Biswell,
. Violations of the fish and game laws are generally categorized as misdemeanors. Minn.Stat. § 97A.301, subd. 6 (2000).
