Reading Roguephotonic's ambitious itinerary reminds me to ask about resupply strategies for approaches to Whitney from the west. First time I did Whitney ('64) resupply by packers leaving caches (particularly for PCT throughhikers) was fairly common and reasonably priced. When I inquired a couple of months ago, the one packer who responded estimated $2000 (yes thats thousand) to drop 20-40 lbs at Junction Meadow (Sequoia NP). Is this really the going rate? Can resupply only be done now by coming out, other than on the JMT? What's the deal?
