It feels like Illumination Night was only weeks ago, but it’s already time for the next lighting of Oak Bluffs: the Post Office Square tree lighting. The Oak Bluffs Association will sponsor this annual event tonight, Wednesday, Dec. 3, at 6:30 pm. The Vineyard Brass Ensemble will play holiday tunes, and there will be caroling and live music by the Brian Weiland Band. In addition, guests can warm up with hot chocolate, and meet with Santa at Dreamland. Guests are encouraged to bring contributions to the Island Food Pantry. The event is free and open to the public.
