Excellent, exciting, enjoyable, and well-managed tour. From the pick-up from an Anchorage downtown hotel with Robert, to the polite and competent helicopter pilot Christian, the polite and helpful helicopter support crew, to the dogsled crews including Elliot and Gabby on the glacier, and the dogs themselves, this was certainly one of the most interesting and entertaining tours we've ever taken. In addition to teaching us how to "drive" the tag sled, Elliot answered our questions regarding the one-person blue huts in which each dogsled crew member spends about a week on the glacier, the kitchen, and how the "restroom facilities" are managed. Great knowledge and sense of humor. Robert, get on that helicopter, and enjoy the adventure! Highly recommended.
