I have some friends who live on the St. Clair River about 20 mintues south of Port Huron. They have a HUGE boat house right out on the river. From the top of the boat house, to the water is 18 feet. That really doesnt seem like alot, but when you did land wrong, it hurt real bad. I couldnt imagin doing 10 meters....that would kill. I remember overrotating a back flip off the roof one time and landing on my back. It stung so bad and my back tensed up so bad i almost couldnt swim.....and thats only 18 feet.... Sure was fun though!!
