"Big D" was our guide, and he was great, and quite knowledgeable with his rounded experience being a former park ranger, as well as paramedic/firefighter. He was very interesting and pointed out many things on our tour. He told us stories and had a great sense of humor. The tour itself was very good, and fun, but slower than we would have liked. Our family has been on other segwey tours before so we were fairly experienced at riding, and wish we could have spent more time riding on the segweys than being off of them. Nonetheless, "Big D" took good care of us and insured a very safe ride. We still highly recommend the tour and enjoyed our time very much. It was a beautiful morning to go on a Segwey tour, which is the best time of day for photos, and also there are less vehicles and traffic in the park. "Big D" is a great photographer, and took great photos of our family on the tour. Next time, we'll try the more advanced segwey tour but we don't have a single regret about the Juniper Loop tour!
