In the late '80s and early '90s some SF personel attended packing clinics in the Rocky Mountain states instructed by civilian outfitters and guides. I guess it was an attempt to relearn things that the Army had let slip from it's institutional memory.

I used to work for a Wyoming outfitter who had instructed some SF. He was kind of a crotchety old drunk, although he knew his way around pack stock. I don't think SF sent teams to him more than a couple of times, for obvious reasons. I believe the teams were from 7th SFG (A).
