Wonderland, Yellowstone in Winter. For those who have taken this trip, I have a long down coat that comes to my ankles. (Daughter says it looks like a sleeping bag swallowed me up.) It provides great warmth but my question is, is it too much coat for this tour? Would a coat that only goes to my thigh (yes, I'd be wearing ski pants) be better suited for this tour's activities? 2. Are ski goggles really needed? 3. Has Anyone used trekking poles on this trip or will Yaktrax be enough? Thank you. Just booked Feb 2024 so need to start prepping now.
