That's nasty......reminds me some folks in a 2wd rear engine rail, trying out Mickeys Hot Tub a few years ago. Dad was driving and kept pulling wheelies (duh) trying to climb out, son had a firm grasp on the cage.......I yelled at him twice to pull his hands inside, luckily he complied before Dad flipped it on it's lid in the tub. After we flipped the rail back over and strapped it out, the son noticed the rockrash on the cage where his hand had been..........and quietly thanked me.
