Having no trick-or-treating this year has certainly put a damper on Halloween. But Mayor Marty Walsh and the city are trying their best to put a good spin on it by holding a pumpkin carving contest. Photo submissions for Boston's online pumpkin carving contest with photo submissions are allowed from October 14 until midnight on Halloween (11:59 pm on October 31). Complete rules and submission instructions are available at boston.gov/pumpkins. Entering your jack-o’-lantern into the contest will make you eligible for the chance to win one of three iPads provided by Xfinity.
