Being able to drive our own vehicle was everything! It was great fun, the four of us were smiling the whole time. My friend and I traded off driving at the stops (always interesting!) while the wives laughed from the back seats (and occasionally closed their eyes lol) Our guide in the lead ATV, Dave, was awesome. He made it crazy fun but also never felt unsafe. He is very knowledgable about the area, the history/dinosaurs tracks (we saw)/movies locations etc. We stopped to watch experts complete obstacles that were crazy! Dave took pictures for us, provided water and just made it great! Would definitely do again!
