Had a great one day tour. Guy Sloan Duvall was our driver and tour guide. He was very accommodating and made sure we enjoyed our trip. He offered to take pictures and guided us to areas where we can get good shots. He is a history buff and he shared some funny insights. One thing he can improve - he should not try to engage back seat guests while driving, he made a little nervous as he gets animated telling us stories and he tended to look sideways to the passengers... while he was navigating dangerous curves as we climbed the peak. Overall, it was a great experience and Guy has great customer and interpersonal skills.
