take a congressman fishing
or any other sort of elected official, local, state, or national, because these are the folks who can get something done if they really want to. it will take a lot of time, like a lot of worthwhile efforts, bit it will pay off if even only a few fall in love with the outdoors. fly fishing trips can be cheap, too, so you won't run up against any of the laws about freebies for legislators. the developers can take people to lunch all they want; it's time for us anglers to schmooze as well.
fly fishing and baseball share a totally deceptive simplicity; that's why they can both be lifelong pursuits.
