My husband and I took a tour of Monument Valley on 11/5/17 with Great Ventures with Sheldon Finkelstein as our tour guide. I can't say how much we enjoyed our tour! It was quite personal, just myself, my husband and one other couple, and Sheldon. Sheldon was a non-stop font of information as we travelled north to Monument Valley. Once we got there, we experienced an incredible tour based upon his expertise. We stopped least 6 times or more for photos and information. We spent over 3 hours in the Valley! After our tour, Sheldon made sure we had an authentic Navajo lunch at a local bistro. On our way back we stopped at Cameron Trading Post for shopping opportunities. At all times Sheldon was upbeat, positive, and engaging. When we return to Sedona, we will most certainly engage a tour with Sheldon agin.
