This week’s Pink Thing of the Day is a Pink-Paint-Encrusted Doorknob, spotted halfway down Freeman Alley — the LES’s most popular street art destination. Who knows where the door it’s attached to leads? Perhaps it’s the entrance to a secret street art speakeasy, where the walls are covered with wheat pastes and the cocktails come in spray cans. Or maybe it’s a portal to a parallel universe where doorknobs play an entirely different role in society.  Stay curious, and don’t forget to get your tetanus shot.
