You know, I would really love to get into guiding. The realities though, there is a significant initial investment involved. Between boat, tackle, lures, insurance, etc etc. The bill can get steep pretty quickly, even for the part time guy. Whether or not you plan on guiding every day or one day a week, most of those costs can't be avoided. Then you have gear replacement, live bait each trip if you go that route. Then you need to make sure you've got a fairly steady stream of clients to get yourself out of the initial debt in hopes of finally turning a profit.
Hopefully my current business continues to do well. I'd like to think guiding could be a very nice retirement hobby. At this point in my life, it's just unrealistic.
