Now through Super Bowl Sunday, Cask 'n Flagon will be trading free appetizers for any new regulation size footballs - inflated or otherwise - dropped off at the establishment's Fenway and Marshfield locations. Once the clock runs out on this promotion (at closing the Saturday before the Super Bowl on Feb. 1), all the donated footballs will be passed to Good Sports, a nonprofit organization that provides athletic equipment, footwear, and apparel to young people who can't otherwise afford it.
