The appellants were convicted in a nonjury trial for possession of 230 pounds of marijuana with intent to distribute, in violation of 21 U.S.C. § 841(a)(1). The contraband was discovered on May 5, 1972, in the locked trunk of an automobile rented and driven by Phillips and in which Tolbert was a passenger, and as a result of an immigration search conducted by border patrol officers at a highway checkpoint.
We know these facts about the search in question. The checkpoint was located approximately 11 miles north of Laredo, Texas, (approximately 9 miles north of the city limits), on highway 35, the main highway from Laredo north to San Antonio. As the crow flies the point was three and a half to four miles from the Rio Grande River, the international boundary. It may fairly be inferred from overall consideration of this and other cases, 1 that the government employs a checkpoint with at least some degree of regularity a few miles north of Laredo on the main highway to San Antonio.
The location at which Phillips and Tolbert were stopped was divided into primary and secondary search areas. At around 8:00 a. m. the officers on duty were conducting what they termed a “blitz,” checking for illegal aliens by stopping every vehicle that came through and opening the trunk of some or all. 2 They referred to this time of *1397 day as the “changeover period” (the appellation was unexplained), and there was testimony that this was a time when many vehicles were coming through and “we have had occasion to have other people try to bring aliens through the checkpoint at the changeover time.” Officers were working in shifts, and the 8:00 a. m. to 4:00 p. m. shift was on duty, comprising at least three officers. Stop signs were up to stop vehicles.
A search of automobiles for aliens under the circumstances of this case is valid. See United States v. DeLeon,
We turn to the sufficiency of the evidence to establish that Tolbert knowingly possessed the marijuana.

Both the possession and the knowledge of possession can be proved by circumstantial evidence,
e. g.,
Montoya v. United States,
Mindful of these commands that we proceed with caution, 5 we conclude that there was sufficient evidence to support a finding of knowing possession by Tolbert. There was evidence which the court was entitled to credit, to the following effect. Phillips and Tolbert had flown together from Detroit to Texas, and they had come together to Texas on this and prior occasions and had traveled about the state together. Phillips had rented the car at Harlingen, Texas, at which time the agent delivered to him an ignition key and a trunk key. There is no evidence that Tolbert ever *1398 had a trunk key in his possession, but he was at the rental agency with Phillips when the car was rented. The two men stayed the night together in a motel. There were four or more large suitcases in the trunk, only one small suitcase inside the car. When the car was serviced by the rental agency before delivery only the spare tire was in the trunk. When told by the officers that they were checking for aliens, Tolbert inquired whether they were searching for drugs. The quantity of contraband was large, the packages numerous and sizeable, and some of them were loose in the trunk. At least one package, about 15" x 10" x 4", was removed by an agent, and at least one of the agents observed through the plastic covering leaves, stems and seeds. An agent felt one of the packages and could * feel vegetable matter within. As soon as access was obtained to the trunk, there was in the rear seat area a heavy smell of mothballs, whose odor is often used to mask the scent of marijuana, and there were moth flakes on the exterior of at least some of the packages.
Both appellants denied the existence of a trunk key. Before entering the trunk the agents attempted to secure a key from the rental firm owning the car, which entailed a delay of about 10 minutes. During this interim they talked separately to Tolbert and Phillips who gave conflicting explanations for their presence in the area. Tolbert stated he was in Texas because of family trouble, while Phillips said the two of them were there for business reasons. 6
Under all of these circumstances the court could conclude that both Phillips and Tolbert had knowing possession of the marijuana.
The cases relied upon by Tolbert do not require a different result. In Montoya v. United States,
In Guevera v. United States,
supra,
a package containing 50 marijuana cigarettes was found on the floor under
*1399
neath the front seat of Guevera’s car, occupied by him as driver and another man as passenger, at a point about midway between Guevera’s seat and'the passenger’s seat and in a position accessible to either occupant by simply lowering his hand. Police arrested Guevera but accepted the explanation of both men that the passenger was only being transported home, and released the passenger who went away not to be seen again. Conviction of Guevera was reversed on the ground of insufficient evidence of possession, there being “no rational connection between ownership and possession of the car and possession of the cigarettes.” The court pointed out that the ear had been unlocked and the cigarettes could have been placed therein by any person. The quantity was so small that one could infer the occupants had no knowledge of its presence. There was no pattern of extensive joint prior conduct. It was as reasonable to believe that the contraband belonged to the unknown passenger as to Guevera.

In the present case, the car was locked, the suitcases were in the trunk, the quantity of contraband very large, a key had been delivered to Phillips but both defendants denied its existence, and there was an extensive pattern of conduct indicating a joint undertaking but with the two participants giving conflicting descriptions of it. In Ledet v. United States,
The agents’ efforts to secure a key from the rental company were fruitless. They then entered the trunk by lifting the seat portion of the rear seat and, with a wrench, unscrewing and removing the back of the rear seat, which made available a structural opening into the trunk area. Through the opening an agent could see packages and two or more suitcases which blocked further view of the interior of the trunk. He lifted out at least one package, tore a corner of a package and saw marijuana within. The entry into the trunk as part of an otherwise valid border search was not impermissible. United States v. DeLeon,
Other points raised by appellants require no discussion.
Affirmed.
Notes
. E. g., United States v. Maggard,
. At some places in their testimony officers implied they were searching the trunks of all cars. But at other places reference was made to “waiving cars through” while the transactions involving defendants were taking place.
. The search in this case was
pre-Almeida-Sanchez,
. No contention is made that the evidence of possession was insufficient as to Phillips.
. See also the comments of Judge Tamm in United States v. Holland,
. Absent other and sufficient indicia of possession, a less-than-credible explanation by one in the proximity of contraband is not alone a ground for conviction. Fitzpatrick v. United States,
