Richard Thayer was a great guide and host and picked us up in Flagstaff. He knew everything there was to know about the Grand Canyon like history, formation of, the rock and minerals involved in the making of and knew all the right places to go. I paid more attention to him than what I did to the teachers in school. I loved the little classroom he gave right there on the rim of the Canyon, we had more hands-on than being stuck in a tour bus. We even had the choice of going to dinner or seeing and feeling more of the Grand Canyon and with Richard being such a great guide we all voted to see and feel more of the Canyon and eat later we did with our own menu picks. The dining experience was fantastic at the Trading Post in Cameron,Arizona I want to go back and try the big taco next time that feeds 4 LOL. One final word, Go with Canyon Dave's Tours, It's The Tour of a Lifetime!!!!!!!!!!! Thank You very much Richard Thayer and Canyon Dave's Tours YOU ARE THE BEST!!!!!!!!!
