According to Ned Tibbits on the PCT_List forum........
"The next worthy resupply route to consider is out via Bishop Pass from its intersection in LeConte Canyon to Parchers Resort a mile down the road from the eastside trail head. Jared, the manager of the resort, is more than happy to accommodate all thru hikers heading up the trail. He will hold your boxes, take you into town (Bishop), offer an inexpensive bunkhouse to "crash" in for a room, there is a laundry facility just down the road, and they have wireless internet (I believe). Good folks, good food, too!"
