When Lucas gets off the ferry and sees Dugan from around 100 yards away while heading towards him, you can see two young men going by when the camera pans on Dugan, but as as Lucas approaches and gets really close up to Dugan, you can see those same two men going by. By now, they should have been some way away and not in the shot. And again, on the next shot, you can see them from back, with inverted positions.
Toward the end, at a customer's house, Ned is struggling to carry Meg and walk upstairs because he said that he hadn't slept or eaten much. But when he and Lucas go to the kitchen, Ned is walking fine, as if nothing was wrong with him.
When running from the police into the park, Lucas has his hat on right before dodging behind the bush. As he flattens to the ground his hat is gone, but in the next shot his hat is on again.
As Lucas opens the building door to visit Meg, he is carrying the stuffed monkey by the back leg. The view switches to the hall, showing him come through the door carrying the monkey by the neck.

When the police arrives at the bank Ned is robbing, Ned peeks through the blinds. Seeing from outside the window, the blinds show bottom sides. The next scene showing from inside shows the blinds again bottom sides which should have been the opposite showing top sides of the blinds.

At the end of the movie when they are heading toward Canada the sign says 13 miles. The mountain you see is Mt. Rainier, but you cannot see Mt. Rainier from the Canadian border.
