A buddy reported this to me in an email.
"I saw a guy almost... well, hard to say what the almost was. Almost died? Almost broke his back? It was a beginner kiter taking a lesson at Isabel/Richmond, and he did this massive jump very close to shore Monday (6/3), when it was howling. I think it was not planned to go so high. I thought he was going to land on the rocks. Fortunately did not. Whew."
A few things are disturbing. I don't think Isabel is a good place for a lesson or to kite period. Plus jumping as a beginner?... Near rocks (there are only rocks there) Plus Monday was very strong wind in Berkeley.
I will try to get more info.
