I was riding at The Rock trail in Gainesville, FL. Theres a ramp/bridge over a fallen tree there. It's about 6' high at the peak. On the second try I went over off the top. The bike hung up and as I fell past it head first towards the ground the outside of my pedal caught below my knee and filleted a huge chunk of skin. My buddy was there with first aid; just gauze and tape but I couldn't have made it without it. We ditched the bikes and had to walk 20 min back to the car. 42 stitches total.
