The PalCo Marsh is looking a lot different these days. Not only was the marsh cleared of the city's largest and most entrenched homeless encampment on May 2, but crews from Figas Construction have now started demolishing the old concrete lumber kilns that have long been dubbed the Devil's Playground. For decades, the kilns have been a magnet for graffiti artists and taggers. But a recent lawsuit rendered them a massive liability for the city, which added a sense of urgency to long-held plans to lay a waterfront trail through the marsh. Check out the slideshow below to see pictures of the graffiti covered kilns as they stood, and as they now lie in rubble.
