The Medford Jingle Bell Festival, celebrating its 24th year, opens its five-day Holiday Tree Display in the Alden Chambers at Medford City Hall. Many businesses, organizations and residents of Medford donate uniquely decorated holiday trees, which are part of a raffle that raises funds to support Medford community organizations. Other raffle prizes include TVs, bicycles, Boston Bruins tickets, and more. Trees and other prizes may be viewed and bid on from 4 to 8 p.m. on Wednesday, December 4; noon to 6 p.m. on Thursday, December 5; 10 a.m. to 7 p.m. on Friday, December 6; noon to 3 p.m. on Saturday, December 7; and 10 a.m. to 3:30 p.m. on Sunday, December 8.
