" We had just one day to see as much of Yellowstone as possible and Clint made sure that we didn't miss a thing! He couldn't have been more accommodating, informative, friendly and professional. If anyone is thinking of saving a few bucks and driving around in a hire car its a false economy - don't waste your time and money! - it will be like watching the world in 2D black and white! Clint brings all of the colour, history and science to the experience to make for a full colour 3d experience that we will certainly never forget. "
