That's a cool idea, make sure it's disposable though I wouldn't leave a DSLR or even an SLR sitting out on a bench.. in my town it'd be taken and sold for drugs lol in 10 minutes flat, in fact, i'd even probably be in the bushes with a 50-200 just to take pictures of the guy who took it to prove that point...Hell even if it were disposable, it'd be taken and sold for drugs ! LOL!

But a cool idea, though, i'm not sure but maybe people would take that as a bit pervertish (I'll be back later this evening to pick it up.")
