I have a few friends who are fly fishing guides and hunting guides in MT. It depends how you look at it, your current situation, etc. they are both single and mid-late 20s. They make a decent living but work hard for it. Use their own clothing, tackle, rods, optics, boat, vehicles.
Every operation is slightly different. They always appreciate a tip. They make the majority of their money in the fishing season. Hunting they’ve gotten gear as tips or part of a tip and often those are appreciated also. Sometimes it’s thoughtful but falls short, ie: a hunting knife (they’ve got a drawer full of them) but a tikka rifle or Swaro binos have been some of the nicer stuff left over. Not by any means is that expected, but they do end up making more on tips over the season then they do a set rate between them and the outfitter. Typically.
