The style of the bike doesn't lend it's self to mounting a tub on the frame, plus this would definitely not be a primary or regular fishing vehicle, but so often a good ride goes through good places to fish. It definitely has no practical off-road capability.
Of course, I may just have to build a five-piece or two.
A right emblem it may be, of the uncertain things of this world; that when men have sold them selves for them, they vanish into smoke. ~ William Bradford
I finally realized that Life is a metaphor for Fly Fishing.
