Back in my youth we were stock car racing on a budget. We towed the car on a heavy trailer designed for farm equipent behind a Chevelle, the trailer brakes if it had any weren't hooked up (no controller in car) and no safety chains. We figured if the trailer left we weren't going with it.
One night we returned from a track 75 miles away at around 80 mph. The next morning looking at the car I noticed a weld broken on the hitch, The end of the ball stud and a portion of the nut were ground off from hitting the pavement, we could only imagine the light show that caused.I am amazed we didn't kill ourselves that summer.
