There is so much to love about POOL, a retail co-op just getting off the ground in a former Mervyn's. The floors are concrete, the ceilings are high, the lighting's groovy, the garage-style windows even groovier. There's a coffee bar with a horchata latte and a florist next door and a farmers' market on Thursdays. And then — well, then, there's work to be done. The booths are mostly occupied, which is good, but we'd frankly like to see fewer electronics and carved wooden giraffes and more handmade goods like the cute baby clothes made from upcycled T-shirts. This place has so much potential, but we wish someone's grandma had bequeathed him the Mervyn's at 20th and Camelback in Phoenix, rather than the one at Main and Stapley in Mesa. This is a tough neighborhood — not even particularly close to downtown Mesa. Home, frankly, to nothing cool. Except POOL. Hey, no one ever thought Marfa, Texas, could be hip and happening. If you build it — and lose some of the tacky imports — we just might come back.
