A few years ago, four of us were packed into elk country in Idaho by horseback and were set up with a sleep tent, cots, cook tent, cooking gear and fuel. (We brought our own food).
We did not see the wranglers for a week, but we had a good hunting experience and they packed back out our critters. Each of us gave the wranglers $100 each and they really appreciated it.
If you have a memorable experience, why not show appreciation for the efforts of the workers?
I have always thought tipping the outfitter was not necessary, but the cooks, guides, wranglers are not paid all that much and would appreciate your tips.
