I've done several regional Senior Games, including last year's Huntsman Senior Games in St. George, Utah (

They're all a blast...especially
Huntsman, which is a fantastic venue, with nearly 10,000 athletes in town.
I'm really looking forward to the National Senior Games in 2009 (to be held in San Francisco), because earlier this year I qualifed to compete in both road racing and time trials.
