Edible? (6/3/07)

The title of this post is intended to gross you out even if the content doesn't. Any guesses? This greenish funky gunk is actually the result of me rubbing my finger across my leg, neck or arm. I think it's a combination of dirt, skin, sunscreen lotion, and maybe more skin. Mmm. This is me sitting in the parking lot at the National Geographic Visitor's Center after watching the Grand Canyon IMAX. Good, but $12.81 for a 35 minute show?
