the hard way. cruising down the highway at 72 mph about 5 car lengths behind semi in middle of 3 lanes with cars on both side, hear a gun shot or what seems to be a gun shot. 100s of table sized pieces of tire come shooting at me like debri from a bad star wars episode with no where to go. luckily i dodged most of the larger pieces from hitting the windsheild, and the only damage i got was about 50 cigarette pack sized black marks all over the hood,mirrors, and bumper
