Acelemist - You're a brave man... I have a 2 car garage, and my wife still managed to accordian the pressure washer between the foundation wall and bumper of our suburban. Any plane stuff goes in the basement away from her and lack of driving skills. She once pushed against the wall with the bumper. I think she thinks it's a damn loading dock or something. If I didn't have to pay all the bills, I'd stick a sharpened 2X4 at radiator height sticking out from the studded wall. She'd never pull in there like that again! I guess I'll settle for the Standard Tennis Ball against the windshield technique.
