Thanks for the great information! Your input has probably saved me a disasterous trip. Being from Florida, the last thing that entered my mind was mountain snow melt effects. As a result, I think I will delay my trip to the August-early October time frame. I am trying to avoid the summer crowds.
I still have a lot of planning to do, but I am looking at the Bozeman, Mt area, Southern Idaho, and maybe Jacskson, Wyoming. Having never been to that part of the country, I am working from a zero knowledege base and am trying to learn as much as I can before we go. Your inputs mean a lot to me. As we go along and I begin to firm up our plans, I will be asking for more help in picking places to stay, guides, etc.
What a great forum this is, Thanks!
