Enjoyed our tour tremendously. Picked up several people in the van and we drove to exchange it for the Hummer. Into Joshua Tree NP, we got a tour that we would never be able to do on our own. This tour does not visit the standard sites on the main road. Learned about the desert, the Joshua tree, the cactus, other plants and trees too. A visit to the San Andreas Fault, a bit of tracking ( we saw some paw prints) and loads of desert information. George was very knowledgable, and the Hummer was a fun ride.
