Yellowstone pack trip advice
I'm planning a trip out west with my 19 yo son this summer (early July). We're already scheduled for a couple of days in UT with my buddy Greg, but then heading up through WY/MT...trying to do a bit of the trip spontaneously but thinking about a pack in (horse or hike) to Slough Creek or other good fishing site. Any suggestions on outfitters, experiences, what to look out for, etc. will be greatly appreciated.
