Turn left at the metal statue of an angler in a cowboy hat hooking a trout. Follow Main Street and pass three fly shops, and in between them the businesses that rely on their clientele. Once the storefronts end, cross the Madison as it passes under the highway, lined by thick snowbanks as March inches toward April.
This town lives on that river, one of the most famous fly-fishing destinations in the world. It brings people to town. Fishing guides and outfitters help open those people's wallets. The ones who don't hire guides spend money, too, helping provide this town with enough income to eke through the winter.
