Walker did a great job giving my fiance and I a desert tour. He knows a lot about history, the plants and animals and I heard a slew of new info. that I'd never heard before. The jeep ride was fun too--- there were big ups and downs on the trail that I'm amazed ANY vehicle could navigate but his jeep did it and I felt very safe the entire time. We saw a desert sunset too, which was pretty. Glad we included this in our trip. Thanks, Walker!
