Freedom knows his street art from his graffiti; who's hot and who's not; what's happened in Bushwick and what's going to happen. In other words, he's a true man of the street art world. Two hours with him will give you an experience you'll never forget. He asked where I was from (New Zealand) and said, "We've got a New Zealand guy here." Now, that's a host who knows his turf.
Easy access by L train (while it's still running) and lots of good food nearby afterwards.
