Treats Truck and TiVo want to keep your blood-sugar level buoyant today. After all, midtown is all kinds of Ernest Shackleton cold right now, and there are lots of holiday shoppers on the streets, and probably also one or two of those giant yeti-like things that tried to snag Luke Skywalker in the Empire Strikes Back tucked along the Garment District side streets. So today from noon to 3 p.m., the mobile baked-goods dispensary will be parked on the corner of 38th and Fifth Avenue. Treats and TiVo-themed cookie cutters for everyone, until supplies run out. The press release specifically says “no gimmicks,” but perhaps you should watch your back, just in case. You never know when you’re going to have to lean on a tauntaun for extra warmth.
