Nothing could have improved our expedition with Jonathan. He picked us up right at 6:30 a.m. at our rented home in Teton Village and proceeded to guide us through an amazing day of wildlife viewing (black bear, moose -- bull and cow, mule deer, elk, pronghorn, bald eagle, heron, bison, pelicans, coots...you name it, he found it and we saw it!) complete with commentary about each animal's habitat and habits. As we made our way through Grand Teton National Park and into Yellowstone, he knew where to stop for the easiest access/cleanest rest rooms (very important!) and hidden, little known sites that we would have missed on our own. He easily obtained information about the time for the next Old Faithful eruption (something we wouldn't have known how to do) and timed our stops along the way so that we arrived at Old Faithful in time to witness this amazing natural wonder. Jonathan was a gracious, outgoing, easy-to-talk with, extremely knowledgeable guide who willingly catered to our needs (mobility issues) and made us feel very much at home. His love of and commitment to nature and the environment were evident throughout the day. He delivered us back to our home at about 5:30 p.m. ... a long, wonderful day with every moment enjoyed completely. Thank you, Jonathan!
