Our group of six truly enjoyed the day. Our Pilot was a wealth of knowledge and gave us a great history lesson about Hoover Dam's contruction and as we moved down the river pointing out the various points of interest. Most exciting was the herd of Big Horn Sheep as many as eleven outstanding. Our Pilot also has a great sense of humor when passing out the towels to help us stay cool. One suggestion is regarding the choice of food for the day. My wife is alergic to Turkey and makes her very ill. Maybe another selection or at least the opportunity to ask for sometihing other than turkey. Overall outstanding day would recommend it to others.
