Any thoughts on this scenario?
Someone in my group gets permits for us starting at Roads End and exiting at Whitney Portal. I don't need a Trail Crest exit permit, correct?
Another in my group gets a permit entering at Kearsarge Pass. An out and back or even exiting at Horseshoe Meadows.
We start at Onion Valley and exit at Whitney Portal showing the appropriate permit depending where we are.

That's definitely an inventive method. It would work, too. Only catch is that to get the actual permit for Roads End, someone would need to drive over and sign in to pick up the actual permit, then drive back.
I did that last year for an overnight permit for Little Yosemite Valley and Half Dome: Drove up, picked up a walk-in permit, then drove home. Drove back next day and started the hike.
