I'm sorting out the logistics of having a friend join me for the first couple of days of my JMT hike (though starting in Tuolumne, not the Valley). I'd like to make it easy for her. So far, the best I have come up with is that we drive to Mammoth (and leave her car there), sleep in Mammoth (or at nearby hot springs), take the YARTS bus to Tuolumne the next morning, and start our hike. This way, my friend will have her car waiting for her upon leaving the trail at Red's Meadow.
What are our options for leaving her car for 4 nights around the following sites: a) Red's Meadow, b) Mammoth Mt., and c) the Shilo Inn (YARTS bus stop!).
Thanks for any info you can offer!
