Puck, I’m doing the same thing. I’m parking at Pinkham on the morning of the 4th of July (parking should be fun) and heading to Mt. Isolation. If I get there early, I might take a side trip to Mt. Davis or head to Dry River Falls. I’ll camp for the night just north of Isolation and the next morning head over to the Perch. I’m hoping for two things. First, that everyone from the 4th of July holiday are heading off the mountain and returning home, and second, that I can find a spot at the Perch, Gray Knob or Crag Camp. The next morning I will head over Adams and Madison and head back to my car at Pinkham.
