Death Valley was awesome, in all senses. Green Tortoise is a really cool travel service. Possibly we were lucky in having a great group of people on the trip (everyone willing to pitch in for meal times and for hauling things on and off the bus when we needed to get somewhere). But we saw neat things, and had a lot of fun, and had surprisingly tasty (and, overall, fairly healthy) food, considering we were cooking it all outdoors over propane.
I think Xta is planning to post a long description with pix, tonight or tomorrow.
