He may not feel as old as other parents, but he's old enough to have retired at age 31. It should be made clear, though, that in skateboarding the word "retire" doesn't mean you stop skating. It simply means he's stopped competitive skating. He still skates almost every day, still learns new tricks, and still does several public demos a year. He was recently voted the best vert skater by readers of Transworld Skateboarding magazine. One of the reasons Tony decided to stop competing at the end of 1999 was that he landed the first-ever 900 (two and a half mid-air spins) at the X Games. The 900 was the last on a wish list of tricks he'd written a decade earlier. The list included ollie 540, kickflip 540, varial 720 and the 900.
