Back in the late 80's, I was making $150/day plus room and board plus tips, which was a great wage back then. Yes we cleaned our own boats, cleaned and froze the catch and on the day they left, boxed up everything for them to take home. It was the best way to spend a summer, great weather and lots of fish made it bearable on the 20th or 30th straight day.
I have been a hunting guide for the last 10 years and I get $175/day plus room and board plus tips. The wage has not changed much, but the days are long and spending 7 - 10 days with the same two guys can get to you, but again, it is another great way to spend my holidays.
If I was a student, or a school teacher with no family, or, like me, with 2+ months off/year in holidays to kill

, I think it is a great way to make money, spend some time in "heaven", see things that others pay big $$$ to see and meet some pretty neat people.
Like most say on here, you will not get rich, but you will get to spend some good quality time doing something you love.
Cheers
