YARTS buses will stop to drop off hikers at some of the trailheads if they can pull off the road safely - I know they do Tenaya Lake and Koip Peak/Mono Pass trailheads when going outbound to Mammoth Lakes.?
But they do not pick up from trailheads.? At their planning session last October, I encouraged them to consider having their drivers evaluate all the trailhead stops to see if they could include more dropoffs and some pickups as "flag stops" - you have to flag down the bus.? It may be that they can do it outbound in some cases but not the inbound due to the layout of the turns in the parking lots. They would have to designate specific spots to wait where they could see you as they approach.? I don't know if the idea is under serious consideration.
Aramark doesn't get paid for the shuttle if they don't run it.
And Peter, I agree it's not a matter of a shortage of labor - it's a shortage of pay.? If the TM shuttle buses are less than 15 person capacity (I think they are) you don't have to have a CDL, so getting drivers shouldn't be that hard.
I've more than half thought about starting a company to run shuttle services during the summer - Lone Pine to Horseshoe Meadows, Independence to Onion Valley, and Bishop Creek assuming ESTA drops that,? Adding the TM shuttle wouldn't be that hard.
