That Scott Macaulay is putting together the 30th Thanksgiving dinner for Melrose residents who for one reason or another will find themselves alone on Thanksgiving Day. Scott said the dinner will be in the Green Street Baptist Church at 1 p.m. but he needs to know how many to cook for. As a result, you must make reservations by Monday, Nov. 23, at 5 p.m. by calling Scott at 781-662-7235 or mailing him at 102 Tremont St., Melrose MA 02176.
