Not sure if yaks are needed...
Boneclave 2001 - We are going to be short by a couple of seats for riders on Sunday, but I don't know if you'd want to bother with the kayak - I wouldn't bother unless you are really dying to use it. If a few people take one half day shift on terra firma (grat spot too) everyone gets a turn out on a boat on Sunday. You'd get dropped off on the way out at dawn, and then jump on a boat when the boats come back in mid-day during the "shift" change.
After Sunday there is no problem. By Tuesday there are more spots open than people to fill them, plus everyone will know where the fish are hanging out.
Special thanks to the boat owners who volunteered to run shifts, this will make a big difference for extra clavers on Sunday.
