Astute East Coasters will notice I am wearing a Great Adventure sweatshirt in this picture. For those of you who don't know, Great Adventure is an amusement park in Jackson, New Jersey--sort of the Garden State's answer to Great America. It is now a Six Flags park that claims to have the "most rides anywhere." I don't think I've been there since getting this sweatshirt, so I can't confirm or deny this--but I do remember that they used to sell those glowing necklaces. What made them glow?
