Well, the Fox is way downtown, so it's not easily accessible for a jaunt down to enter a lottery. There's also really not much to do around there while you wait. You can't really get down there without a car (the bus goes that way, but public transportation isn't really utilized around here).
Also, for all the publicity the show's been getting here, the lottery hasn't really been advertised all that much.
