When Summer returns Seth's stuff in episode #2.1, a record in the box jumps from at her stomach level to covering her chest between shots.
Two girls walk into the place that Seth and Luke work at in Portland. Just before one of the girls mentions her fake ID working in SE the night before, there is a shot that pans across showing them walking in, and in the background, what should be the Willamette River. In the shot, the cars in the parking lot appear to have Oregon plates, but you can see palm trees in the distance across the river-there are no palm trees in Portland.
