My now deceased uncle was written up by the US Army for breaking his leg by wrecking a 'Go kart' that he and his buddies had built. It had a traverse mounted 4 cylinder jeep engine with a jeep wheel and tire directly mounted in place of the flywheel. It was push started and had a single scrub brake! He lost it and stuck it in the side of a Nike Hercules transport. (Korea) Makes for a good story now, but wasn't too funny at the time. He got nailed for the old "destruction of Gov't property". He spent a good amount of time walking guard duty around the inside perimeter of a Nike installation. He said you couldn't see into the dark past the fence, but he was in almost daylight bright lights.
It bothered him at first, but after a while he said he didn't care because it sucked so bad. He did manage to eek out an honorable discharge. I sure miss him...
