Dora picked us up promptly at the assigned time and entertained us from the moment we met with historical, geographical and geological information. This woman is a walking encyclopedia! Out tour began at 8:30 AM and our day ended at 5:30 P! And what a tour it was! This was the best day, bar none, of a two week touring vacation. If we ever return to Williams, AZ, Canyon Dave's will be at the top of our list of things to do, and Dora will be our requested guide. Thank you so much for making this leg of our trip so memorable.
