Here is an article oabot the soven brothers competing in Orlando from www.orlandosentinel.com.
"Brothers Phillip and Bob Soven of Longwood won quarterfinal heats in wakeboarding Saturday at the sixth annual Air Nautique Wake Games at the Orlando Watersports Complex. Phillip Soven scored a 78.33 in the 10th and final heat. That was the third-highest score overall in that category behind Trevor Hansen of Groveland and Harley Clifford of Australia, both of whom registered an 80. "It's a little bit of a home-field advantage, but once you get out on the water, no matter where you are, you have to focus on the task at hand," said Soven, ranked No. 1 in the sport."
