Edison nestles into the watery-green Skagit County farmlands like a lazy bend in the slough. At 11 a.m. on a Friday, you could be the only person walking around the old-fashioned storefronts and tangled, art-filled gardens. But foodie journals and lifestyle blogs have been discovering Edison for years now: a tiny hamlet (it’s not officially a town) filled with more artists, artisans and chefs than you’d think possible, yet still keeping its offbeat, dusty-saddle charm.
