I"m jumping in my backyard. I have this 3ft retaining wall and I was jumping that, but on the top, there are huge landscaping rock. Well after getting some good jumps, I try to do a flip or something. This jump is big, and I end up doing half a flip and I land on one of the rocks! MY truck flips over, dead. THe rock busted my Cooling head into pieces and the shock tower was something of the past! Just a few bucks in damage, but I thought it was worse.
