Sweetness... I tried that once but I just drank the beer. lol j/k.
I collect alot of stuff, although beer cans arn't one of them. I like collecting Die Cast cars but I've been limited to that due to expense. =) I have a bunch of old Coke Cans and bottles downstairs. You have to be careful with the cans though, they can explode if you store them in a warm climate.
