This was my first JustYou tour in October 2011.
I contacted the Wyoming tourist information and they thought it was late in the year for Yellowstone but,while the weather was cold in South Dakota, which added to the Badlands experience. When we got to Little Big Horn, it was a warm and sunny morning. After lunch in Billings, driving towards Cody, the clouds over Yellowstone looked ominous and the was snow overnight, but, it was a sunny day in the Park. We were told later that the road to Jackson was blocked,but, we stayed in West Yellowstone and it had cleared the next day. Jackson was cold,but, from then,the rest of the tour was in warmer weather.
