According to this, he was a guy who lived on the river 20 years. I'll check with my Dad, he grew up near by and was one of the first to routinely float the Deschutes (before rafting became a sport for the masses). http://www.catlin.edu/news/outdoor-program-ms/deschutes-river-october-2005
The bet ends at the conclusion of the regular season. The Avatars are then changed and stay throughout the playoffs. Cool? Also, bet is called off if either big man plays in fewer than 60 games. I don't want to be celebrating an injury to Bynum and my guess is you feel the same way.
loved the pix from your link... I know right where most of those were taken. I especially liked the one of the kids free floating Buckskin Mary as I've done that quite a few times. Fun times. STOMP
