I was just looking at the rules--I like that they specifically ban Hummers & Ford Excursions! I'm glad you got an experienced crew person, that was incredibly helpful for my brother-in-law when he did it last year.
What the route maps don't show you is the headwind that seems to have come up the last couple of years. I'm not sure if it's in the same place, but it seems that the riders whose slideshows I've seen had a worse time with that then some of the climbs. I hope it's mellow for you this year.
Edited to include: Does this mean RAAM is in your future too?
