Billy was a great Tour guide. He was very knowledgeable and super funny! His main objective was that we were safe on the mountain. Being a self-guided tour we were a little nervous, but he was very informative and reassuring that we would be able to complete it. I am not super good on a bike, so I was nervous. We had no problems! He also made fantastic suggestions regarding breakfast donuts, and coffee in the cowboy town. Thank you!!
