John Brown Smokehouse is throwin’ a hootenanny this Wednesday. Actually, it’s more of a pig picking. To commemorate Harper’s Ferry Day the Long Island City ‘cue spot,which has become something of mini-museum of ephemera devoted to abolitionist John Brown, will be smoking a 200-pound hog. And not just any old hog either but a very happy heritage breed pig from Tamarack Hollow Farm in Vermont. Pitmaster Josh Bowen has enlisted the aid of Tyson Ho, who knows a thing or three about cooking whole hog. The not-so-little piggy will smoking out front of the restaurant all day and should be ready to serve by late afternoon, $20 all the pork you can eat. Rumor has it that Bowen’s, banjo picking alter ego, Trainwreck Washington will be making an appearance.
