This is what happens when the lake level is very high, due to all the rain we got in Texas and when you are riding an 07 Transcend with all that POP.
The rider is doing as well as he could be at this point and says he will be back on the board as soon as he is able to walk again.
The quality of the vid is not the best, it was shot on a camera phone, they were not thinking anything like this was going to happen.
WARNING, KIND OF A GRAPHIC VID, SOME MIGHT NOT WANT TO WATCH!!!!! http://www.youtube.com/watch?v=OewjKND6fUw
