Ryne......being a guide is far from having fun.....though it can be.
I use to be one, and it's a lot of hard work. Long hours scouting, setting up and tearing down decoy spreads.
Mind you...you won't have to do that everyday.....but more frequently than you may realize.
There is so much to guiding than I really want to mention....but I would be here half the night.
Start with your DNR, and see what they recommend for lic. and fees to become one. They should be a pretty good place to start.
I'm not trying to sound negitve....just realistic.
Have fun...and good luck to you.
