This guy is a master at coordinating a three-generation Yellowstone trip! In August our family, including grandchildren ages 14,11, and 9, spent two fabulous days learning about Yellowstone with MacNeil. He turned the geology of Yellowstone into a science lab, on a walk we “discovered” a Bison carcass, and all of this plus plenty of fun and a great breakfast to meet the needs of all ages. He is a smart and funny charmer. Don’t even think about going to Yellowstone without talking to MacNeil first!
