Continuity mistake: In the Pacific Playland scene, Wichita and Little Rock are seen riding a Swinging Ship when all of a sudden, zombies begin to pile over the park's fence. In the next scene, the two girls are shown running down a stretch of walkway shooting at the zombies that are chasing them. When the camera is focused on the zombies pursuing the girls, in the background (top left corner) you can see the Ship ride sitting still. After the camera gets a shot of the girls, it goes back to the shot of the zombies and the Ship is now moving in full swing. The next time the zombies are shown, the Ship is sitting still again. There was no time between shots for the ride to have started and stopped so quickly.
