We were out filming several cars off road, when we came across some guys riding on dirt bikes. i started to film them doing some stunts when one of them fell off his bike. at first the crash didn't seem that bad, that was until he pulled up his shorts. his leg hit the peg pedal and slashed a piece off his skin so deep that you could see a bone. we tied a tshirt around his leg to prevent it from bleeding and took him to the ER. he also hit his back really hard and was in a lot of pain, both from the leg and his back...
