The way the course snakes around you can always change your mind mid-course. The 65 and 100 miler share the same rest stops. The 100 miler visits the lunch stop twice, before and after the loop through Whydaho.

I need to go track down the map. It probably has more info about start and close. I suppose if you have your reg packet early you could start. Just beware that the rest stops might not be open,k but I know you know that.

TrekHawk, just keep you tme in the rest stops very short. The only one that was crowded was the first one. Petunia and I didn't leave until 8:30 or 8:45 because we screwed around a lot and stopped for photos which means we hit the first stop with everyone. If we had left on time we would have been ahead of the crowd. Now, mind you, there were only 875 or so riders so "crowded" is relative. As usual though, it was the line for the elephants that was the problem.
