In the beginning part where they play the music... In one of he shots where you see them driving, I think in the mountains, and Debbie is reading a book or something, with her legs crossed. If you look at her shoes they are red and the shot backs up a little, and stops. BUT WAIT!! When the shot backs up when Debbie is sitting there, her shoes change black for a few seconds and then turn red again. You can't miss it.
