Foraging in Prospect Park with Steve Brill

"Wildman" Steve Brill is a fellow who knows how to live off the land. He's a gatherer in the original "hunter-gatherer" sense, and travels Connecticut, Pennsylvania and New York teaching people what exactly is safe to pick up off the ground and eat. Prospect Park, it turns out, is full of edible wonders including hedge mustard, black walnuts and giant check mushrooms.
