DAVE - Wife was telling Me of an incident here around Madison, WI. recently where a 17 yr old was killed batting mailboxes. He started falling out of the car, the driver grabbed Him but swerved the car causing loss of control, hitting a tree. Driver walked away unscratched but the Kid in the window was killed. Buy a cheap mailbox for them to beat up and be done with it. Guy who's house We rented in Freeport had a 1/4" plate mailbox mounted on a grain auger spiral, but the shaft was 2"+ solid steel set in concrete 5 ft deep. I sure hope the Township Snow plow never hit it because it would have wrecked the plow!
