Derick was our well informed and personable guide for the 3 1/2 hour cultural tour. He knows the history of the valley as well as adding his own personal family stories. The highlight moment of the tour was Derick playing the flute in the Big Hogan. We would have enjoyed an even longer concert. We also visited a working family's hogan in the valley. Derick met us at the hotel on time and we returned to he hotel at the time promised. We made many stops and he waited until we were ready to move on to the next place. We never felt rushed. It was a memorial day. Thank you.
