Finally got around to finishing the read. Sounds like you guys had a great trip.
The funny thing is I know the areas you were riding through, except from the pavement side. We did the Oregon desert northward in August. Passed through some of the same little towns along the way. Mostly kept off the dirt since I was on the Ducati.
Definitely going to have to get down that way on the little bike.
P.S. With all my touring experience I'm still trying to figure out how to pack reasonably on such a little bike. I'm curious what you brought for all that camping. Was it more, or less, than your 'big loop' list?
I guess one good thing about the desert at the right time is you don't need much for rain or poor weather gear.
