Chattanooga, Tenn., is a town that loves its art. (And its doughnuts, but that’s a different post.) Art is everywhere here. It oozes out of museums and galleries and spills out onto walls, buses and anywhere there’s an inspiring blank space. Such as sidewalks. In the emerging Southside Art District, for example, simply walking along immerses you in all sorts of innovative artistic minds. Sculptor John Petrey, for instance, is known for his dress series, and one of his astonishing works is just standing right there. You can walk up to it and inspect it and touch it all you want. Yea, art for the people!!! And then there was this wooden door propped up against a lamp post on a sidewalk in Northside, Chattanooga’s cool hipster alter ego. Younger Daughter and I were walking to Greenlife Grocery (which we all know is actually a Whole Foods, although everybody in Northside tries to deny it) when we spotted the door and tried to figure it out. Was it art? Apartment renovation? A magic door that would lead to an alternate universe? We resisted the urge to draw on it since all we had were ink pens and lipstick and, besides, if it did happen to be a magic door leading to an alternate universe, we felt that non-engagement was the proper response.
