Tying my own flies versus buying them. The math works out in my favor if I’m disciplined about buying materials and working in materials from craft stores and from hunting. I buy premium fly line on closeout and that saves a lot. Building leaders from cheaper brands of fluorocarbon saves over buying premade ones. My kayak was a closeout model and was 30 percent off retail. Freeze gallon jugs for the ice chest instead of buying ice. Fish close to home instead of driving hours to catch the same exact fish. I never got driving halfway across Texas wasting tons of time and burning all that extra gas when there’s the same fish to be had nearby.

Frugal ... well, how about getting the boat paid off and keeping it instead of trading in on a new one every few years?

I gave up on tackle boxes/binders for all soft plastics, hooks/some terminal tackle. I just put the bags in a gallon ziplock bags. Mostly for ease, but it saves money.
