I've managed to do some marginally interesting things in my sporting life...
Climbing several mtns, Twice completing the 12 Miles Of Hell Mtn Bike Race at Ft Sill, OK (usually 14-17 miles of pure riding hell. I only threw up once during both years), Cliff jumping on skis at Taos (bent skis), Jumping off a cliff into the Arkansas River just upstream from the Royal Gorge (big time wedgie), Going FULL speed on GS skis in tuck position straight down Lower Valley View at Steamboat (briefly thought I would die), playing golf with George Mark (briefly thought I would die), playing basketball with Barry (briefly thought I would die)....

This cool video tops anything I've ever thought of doing.
