Greg was a wonderful tour guide - very knowledgeable of the area and quite flexible! Despite the downpour, Greg happily agreed to take us on a great easy hike around Leigh and String Lakes in the Grand Tetons. It was so beautiful, even in the rain! Can't imagine what it would be like with blue skies! Very nice that he provided binoculars in his van for his passengers to use. He went over and above to get us to all of our other requested viewing sites so we could take photos. Our personalized tour exceeded our expectations. He was easy to communicate with prior to the booking, friendly, and very professional throughout the tour. Even after he had dropped us off to our hotel following the tour, he called to report that there was a beautiful rainbow in the sky! We took home great memories of our Grand Teton National Park tour with Greg.
