7-15 to 7-18.  Glacier National Park.  It truly was the granddaddy of backpacking parks.  I saw: moose, griz, elk, dear, goats, waterfalls, loons, ducks, and alpine chalets.  The chalet was incredible.  It overlooked the "American Alps" and had the best views that I have seen in the states.  I also liked the fact that all of the campsites had food prep areas and food poles.
