Oh, sorry, forgot to answer Charlie's question about our sleeping arrangements.
All the riders will be camping (if they want to) on the lawn next to the Merkle building -- 7001 Columbia Gateway Drive. So the route won't literally go in front of where the tents are.
Family and friends are encouraged to support riders, but I don't know the details on where they let you go. I know they don't want non-participants on the course, which is closed off with cones. (Basically, as I understand it, it's one lane of the Columbia Gateway loop; the other lane is open to car traffic.)
There was a map on the Booty Web site -- I forwarded it to somebody, maybe Bob? a while back. It's hard to find, though (their Web site layout isn't the greatest, IMHO.)
