"Fishing for a living" and "taking people fishing" are two TOTALLY different things!
I've been a guide on Quinte for the past year and a bit, and as much as I enjoy it, it's really a lot rougher than most people think!
Super early mornings, very long days, lots of prep (scouting, studying maps, etc), lots of setup (rods/reels/baits/planer boards, etc), lots of time away from your family, expensive to run (insurance, gas, tackle, bait, rods, reels, boat payments, truck payments, hotels, etc). Not to mention the PRESSURE to catch fish that's on you when people are forking over a few hundred bucks per day to come catch fish!
Do you have any idea how HARD it is to sit back and watch people catch MONSTER fish all day long, and NEVER get to reel one in?? Sure you're out on the water, but your not "fishing". That's a lot harder to deal with than most people think! This past fall, I had 14 fish come in my boat that would have beat my personal best...and I didn't land a single one of them!
Don't get me wrong, it's a heck of a lot better than a lot of jobs out there, but it's not think walk in the park that people think it is!
