Three years ago we were standing at the back of our trailer and next to us was a real clean nova a guy raced. We were all standing there talking and then we hear glass break and see the back window blow of the nova gone. We got to looking and found a lug off a converter in the car. Apparently it came off a dragster (we think was running on the track at the time) and managed to be thrown about 30 yards off the track thru the guys window.
