Hi Pauline and Linda. I've just received the tickets and info and am trying to decide which of the flights to do. I wasn't too concerned about a balloon flight but a colleague said to google Teton Mountains and Jackson Hole.. STUNNING..Will definitely be doing that one! Also, the 2hr flight in the Grand Canyon could be turbulent re thermals in the heat of the day, .. Enough said!.. I work at the Jersey Met Office.. Pack for cold, and hot!! See you soon! Rose
