When you can’t make it to the game, where do you watch the Redskins? Send us your images from fan gatherings in D.C. and beyond on Instagram or Twitter with #WPSkinsFans, or e-mail them to goingoutguide@washpost.com (Juana Arias/For The Washington Post)

Read on for game-changing local grillables, beer, apparel and accessories for your tailgating mission.
