did same knee blowout playing high school football. MY best is: Tried to throw rodeo off cliff @ Bridger Bowl and was so stoked i flipped upside down and knocked my self out with my fist starting spin, fell like 30 feet upside down and slid like 200 yards unconcious, broke my face in three spots, full face helmet was shattered and pieces were stabbed into one knee and my neck.Knocked out for almost 10 minutes, scary shit, came to almost three hours later, enough time for my ma to fly from Denver to Bozeman.
