I'd been wanting to return to Moose Creek since Doug and I last visited in 2005.  The scenery is stunning and it's located in the Selway-Bitterroot Wilderness area, so you're not likely to see many people there.
  Being a low elevation strip, you have to visit either very early or very late in the season.  July and August are just too hot at that altitude.
  We finally had a combination of a mid-June trip, spare time, and cool weather.  It was well worth it.
