No matter what kind of day you're having, out on the San Francisco Bay, just off Treasure Island, Captain John von Tesmar has a guaranteed way to lift you up.
For nearly two decades, von Tesmar, the owner of Kite the Bay , has been teaching people how to harness the wind.
"There's no rules, there's no road signs, there's no traffic laws," he said.
Picture a snowboard, but on water. Now add a kite the size of a small car, and you've got kiteboarding, a sport catching wind all over the world.
But don't let the casual-sounding name fool you. This sport blows people away.
Just ask Jose Urrea, a Colombian tech salesman who, between meetings, trades his business suit for a wetsuit.
"I feel this freedom and this peace. Once you try it out, you wanna keep doing it," he said.
