We'll be out there in less than 3 weeks, sleeping 5 nights at Mammoth Lakes while dayhiking in Yosemite... After 5 nights in Mammoth, we'll shoot down to Lone Pine and plan to do the Whitney MR and Langley - weather, permits and legs allowing.
I plan on camping at Upper Boyscout Lake July 14 & 15. We plan on summiting on the 15th. Any chance you'll be there?
