The D.C. Metro area includes stores up to Germantown (this includes the Germantown location), but does not include Frederick locations. Baltimore and Annapolis area Chick-Fil-A locations will not be participating in this promotion.
What’s the catch? You must wear some sort of Washington Capitals gear (hat, jersey, mask, socks, etc.).
Call your local Chick-Fil-A to see if they’re participating!
