We ride an 08 Ultra, two-up, pulling a Timeout Camper. Planning a trip in August from Manitoba,via Sturgis to Colorado. Durango and Four Corners, then up through Utah to Grand Tetons, Yellowstone, and up to Alberta. Any must sees? Anything to avoid? Any cautions? What kind of temperatures can we expect in Co & Ut? We still have lots of snow and -15 temperatures so all I can do is sit here and plan. Thanx in advance.
