In the back, on the left, Paul who opened up his shop to Mark and stayed to help instead of going to the salmon barbecue he was supposed to go to. Thanks for the shop, the tools, the friendliness, and for not laughing too hard at those 4 or 5 clowns trying to wrestle that tire...
Clif is trying to nail Daniel Bannon's boots to the tire, to avoid a repeat of the incident on the old one. (This was Daniel's first ride up to Alaska, and Clif led him up there for his first SS1K - congrats!)
