Folks... I just completed a backpack from Agnews Meadows to Tuolumne Meadows (we ended up at the Mono Peak Trailhead).
First night we camped at Gem Lake
Second night at Algers Lake
Third night at Summit Lake (after going over Mono Pass)
We left our cars at the trailhead in Tuolumne, and got a ride via Lucas at MAWS Transportation:

He was awesome -- showed up on-time (he was there when we arrived), his van was spotless, carried 7 guys plus packs with some room to spare, and was the pinncacle of service. He took us first to pick up our permits, offered to stop someplace for breakfast, etc. AWESOME and I'd highly recommend him if you need shuttling in the Mammoth/Yosemite area.
