The Weymouth Food Pantry has been looking for a new location since learning that its home for the past 27 years will be put up for sale. But the Immaculate Conception Parish Hall -- located behind the pantry -- will be put to use Monday for the pantry’s biggest annual fund-raiser, the 18th Stock Our Shelves Walk. The 2-mile walk begins at 10 a.m. and is designed to increase awareness of the pantry, which is in the parish’s former school, as well as raise money. The pantry serves more than 400 families a month. Find more information and registration forms at www.weymouthfoodpantry.org or call Barbara Hughes at 617-529-3080.
