How Explain Fishing to Someone Who Doesn't Fish?

Think I'll fish the canal soon. Winter felt very long as I tended the rod here in the middle of it. It's been good, every visit, but I think once or twice walking the tow path and pitching for pickerel will mean more involvement and interest. How do you explain that to someone who doesn't fish? 

In everyday life, there's never occasion. Fishing's like music: rhythm, tone, variation (of melody, instrumentation, voice). Fishing involves rhythms of walking, casting, wind, responses from fish. Involves water tone. Temperature has a sort of tonal quality. The sky has tone, and plant life, rocks and soil. All sorts of inner emotional responses to environmental variations can elicit melody. There's nothing like stepping away from distractions (road sounds tend not to be healthy and countering this by radio or c.d.'s can tend to get desperate). You move into a natural environment where ideas emerge without the performance demands of the road. There's a difference between highway thoughts and thoughts when you slow down and absorb a large environment. We all know about road rage. I've never met a fellow angler out here in such a mood, not even in stormy weather. The closest we come to that involves the exuberance of fighting a really big fish, but rage? Nah.
