shuttles from Ashton Id to West Yellowstone

[J Griffin]

we're contemplating doing the Yellowstone branch line on our fatbikes later this Summer, and I wonder if anyone knows of the possibility of a return shuttle from Ashton.  I expect we'll camp on the way down and do some fishing.  I'd rather not have to drive two vehicles from Central Washington all the way to West Yellowstone if I can avoid it though!
