3. Kiteboarding with Extreme Sports Dallas
Chances are, kiteboarding wasn't your sport of choice in high school (mainly due to the lack of cheerleaders). But no reason it can't be your elective this year with lessons on Lake Ray Hubbard that include four-line inflatable kites, gear, on-the-water radio communication, and chase boat support. Wait for wind and catch a wave.
One-on-one lessons $150-300 here.
