We had a wonderful half day tour with Ron. It was the perfect way to experience Joshua Tree National Park, without having to figure out where to go, how to get there, and what to see! Ron knew so much about the Park, it's history, the vegetation, rock formations, etc. etc. Even on the drive from Palm Springs to Joshua Tree, he was able to tell us so much about the desert and everything we were seeing out our windows. He is a terrific, experienced, knowledgable guide and a pleasure to be with!
