Here's my killer crash while 'water skiing' at Arapahoe Basin (full-res version here). Yes, my bindings were a bit loose. I improved significantly that first season in Colorado ('05/'06) so I've subsequently tightened up the bindings a bit to deal with the fun of attacking double-diamond runs.
Jiri was nice enough to videotape it and send me the clip. Here's his entire run (requires logon).
