I won one of the "first prizes" -- a flip video camera -- in this summer's Wheat Thins Bonaroo Festival contest. The weird thing is that they did not not notify me -- it just arrived by Federal Express.
Not the same thing, but I've also got a couple of local prizes:
A few years ago I won a $25 gift certificate to Concord Mills Mall at a nonprofit's volunteer appreciation event. It was about the time construction the mall began, so I got to wait a long time to use it.
When I was in college at a major university, almost no one had their photo made for the yearbook, so the staff came up with some prizes as incentives. Everyone who had his/her photo made was in the drawing. I won a Schwin bike. I was a senior and really didn't want a bike, so I sold it back to the guy at the bike shop.
