$225 sounds quite high, while $85 for a service coming in from Independence sounds low
in 2010 I paid $375 to bring 3 people from Whitney Portal all the way to Tuolumne Meadows. I also paid just $70 to be picked up from Sawmill Pass trailhead and back to Lone Pine in 2009, although he was on a run to drop some folks up there anyway. All this was with Bob from Whitney Shuttle.
I will have to check out the outfit from Independence. Competition and more choice is a good thing, though. Having another number to call when you arrive at some trailhead you didn't plan to exit is a good thing.
