I used to play submarine with shopping carts...I'd grab the side of a cart and peddle my ass off towards my intended target (usually a gaggle of other shopping carts...or the store weenie who was hollering at me to stop) then let go of the cart to let its momentum take it (hopefully) into the target. Did the same thing in a car when we were kids too. Does that make me a submarine driver...or just a dick?

If guns are outlawed, only the government will have guns. Only the police, the secret police, the military, the hired servants of our rulers. Only the government -- and a few outlaws. I intend to be among the outlaws" - Edward Abbey
