What can you do with a vacant lot? Urban activists in Louisville have set out to show just how much with an ongoing pop-up festival of sorts at 615-621 West Main Street, an empty plot of land in the heart of downtown where REX's Museum Plaza skyscraper was once set to rise. They're calling it ReSurfaced. The mission is to repurpose a downtown lot as “an urban laboratory for innovation, community gather, and as an entertainment venue, showcasing our local creativity, breweries, and talent” for five weeks. Open Thursday through Sunday each week through October 25, ReSurfaced events include hip hop concerts, Shakespeare performances, puppet shows, a Pecha Kucha conversation, and a beer garden. According to the event's Facebook page, ReSurfaced is about “Transforming and activating our underutilized surface lots and vacant spaces to bring back the walkable urbanism Louisville once enjoyed.” Louisville has thousands of vacant lots, a problem that earlier this year prompted the city to launch "Lots of Possibility," a design competition sponsored by the mayor's office.
