Racquetball . . . talk about a great workout. My friend Jim Ansite is the best. I started playing racquetball in Manhattan Beach at the MB Athletic Club (?) with Jim in the 70's. Don't think I ever beat him. Played on and off from then on and played more at our club in Fair Oaks and at the Gold River Racquet Club with my neighbor Steve Brown. Loved the game and got OK but nothing great. Still love to watch it played and the pros are just amazing.
