[Tagging] Tagging for a pack station?

[Tod Fitch]

ref: http://en.wikipedia.org/wiki/Pack_station

I assume it should be tourism=something but what the "something" is is not
obvious.

Nothing shows in the wiki or taginfo that I can see or "outfitter" or
"pack_station", etc.

>From Wikipedia, it seems this might be a regional name but the hints on
what this is called elsewhere did not help me much either.

Thanks!
Tod
