Visible crew/equipment: While in the pot field, just as the growers are about to shoot them with the laser sights, you can see a crewmember crawling by in the background.

Continuity: We see Tom standing in the river catching fish, yet when they start running from the bear, the water is gone.

Other: When they're with the women in the redwood, the one says that she's "all natural" and shows her hairy legs. Later they are both dancing around with their arms over their heads and their armpits aren't hairy. If they were "all natural" they wouldn't shave their pits either.

Revealing: Briefly, while Seth Green was being pulled from the river, you can see that the rope behind him is taut, nearly perpendicular to the current. He was pulling himself across a rope that was anchored on both sides.

Continuity: When the trio fall down the shaft, a small wooden beam falls on Tom's leg, but when the shot changes the beam is next to his leg.

Continuity: In the scene where Tom, Jerry and Dan go into the tree house after the funeral, it is dark and they have flashlights. Then a second later it is light outside.

Other: After the funeral, the guys visit the clubhouse. They open the box for DB Cooper's treasure. The blood they used to sign their blood oath is too red to have been 20 year old blood. It should have darkened to deep, deep purple or brown by now.

Continuity: Right after the 3 guys fall off the waterfall, Tom lays on the ground. You can see that his pants have a lot of dirt on them. But in the next scene Tom is getting up to make his point to Dan, and there is no dirt on his pants.

Continuity: Near the end, when Tom, Jerry, and Dan are about to be shot by the two hillbillies and the cop, there is a brief scene that shows all three guns being loaded from a side view. The gun closest to the camera is a handgun. When the camera zooms out, all three men have rifles. There is no handgun to be seen.

Plot hole: The Hillbillies take a "short cut" to catch up with the guys after they are taken in by Burt Reynolds. However, the guys get a chance to sleep comfortably until morning before being confronted by them.

Visible crew/equipment: When the 3 guys are in the pot field, Dan dodges the bullet, you can see the camera's shadow pass across him.

Other: As 2 of the trio are in the store just before meeting the cop, one is on his cell phone. In one of the frontal shots of him talking, you can see the other two approach from behind then suddenly back up quickly. As said on the commentary, they didn't get a cue to go, and then realized they were wrong and backed up.

Factual error: The hairy girls claim they are in a giant Redwood named Earthchild. The only Redwood trees in Oregon are in the far South West corner very near the coast and mostly over the border of California. D. B. Cooper was supposed to have landed North of Portland.

Continuity: The Bear ate Dan's cell phone and it was in her stomach until Jerry found it in the bear poop. There is a picture of a bear on the cell phone screen, after Jerry becomes overwhelmed with the fact that Denise broke up with him - but there wasn't any chance for a picture to be taken of a bear.

Continuity: In the pot shack scene Dax Shepard is holding the package of pot to his side, you see him slowly move it behind his back to hide it from the two hillbillies. In the next scene, after they flash back from the hillbillies, it's back at his side and he's once again slowly moving it to his back. Shepard, and the other cast, admit this is a mistake in the commentary.

Factual error: During their first night's camping, they encounter a bear..a Kodiak bear. Unfortunately, the only bears found in Oregon's Cascade Mountains are black bears.

Continuity: When Tom, Dana, and Jerry go over the waterfall, the canoe breaks apart into three pieces upon hitting the bottom; the next scene, when they are on land, the canoe is in a multitude of pieces.

Factual error: When the 3 guys have just safely gone through the rapids, they hear a roaring sound. This is leading to a waterfall. The water around them and the leaves in the water are perfectly still. A few seconds later they are going over the waterfall. A river just before a waterfall would have a strong current leading to the waterfall. this should have been the case with the river, but there was no current whatsoever prior to the waterfall.

Continuity: When the guys are in the tree house right after Dan tells the girls about using the pussy willow reeds you can see Tom just about to take a drink from a canteen, then maybe a second later in the very next shot it shows Jerry taking the canteen from Dan and passing it on around the circle.

Continuity: When Jerry is using the radio, the cord has a little bit of cloth near the mic end. Then when Jerry gives the mic to Flower, to give the location, the whole cord is covered in cloth.
