ripping in the dunes and hit a huge rock hidden in the sand , rolled a few times . When i stood up a bone was sticking out of my shoulder and still had over a mile ride to the trucks. Long story short it hurt really bad and didnt ride for 8 months but had some time to fix up the shee luckly the damage wasnt much, more damage to me 10,000 worth of medical bills and some messed up xrays
