Some things change and some things don’t. One of the things, recently, that doesn’t change at all is the ability of both adults and children to go exploring in the environmentally-challenged, and currently abandoned, Whole Foods site in Gowanus. It’s been open again and again. Of course, it’s just an empty lot and it affords photographers some different angles on the Gowanus, but it’s also a contaminated property that wasn’t fully cleaned up before the grocer put the brakes on the project. Perhaps the lack of a secure fence is one way the big chain is trying to show the property is actually safe. If kids can hang out there, what the problem with selling organic grapefruit there? The most recent building plans filed by Whole Foods with the Department of Buildings were rejected in December.
