Agreed, very inventive, but I would bet that if you tried something like that over here you would have an anti terrorism squad kicking down your door and end up on charges.Our caring government doesn't like us to enjoy ourselves too much nowadays. If you are in the mood for silliness check out the Bowling Ball Cannon on Youtube, another bunch of Yanks with too much time on their hands and wide open spaces to mess around in, lucky b*****ds.
