Rita Giancola, 89, decks out her Lexington Street home as “Christmas House” every year. It’s an over-the-top display of lights and figurines and decorations. She’s been doing this since 1978 and uses it as a fundraiser for local food banks. The open house is Dec. 18-22 from 6 to 8 p.m. Admission: non perishable food items, household items, and donations for hams and turkeys.
