Yeah, now that you mention it, they do. When I was in Green Bay to watch the Packers-Seahawks a few years back, prior to the game, I was mingling with the pregame crowd and sat down at a table with both Hawks and Packers fans, our fan ID noted by our 'colors'.
All they sold was canned beer as it's a neighborhood stadium with no nearby permanent restaurants or bars, just temporary structures and seating, and I bought one with a label that said, "Green 19".
A couple of Packers fans I was sitting with began to tease me, saying "Look, he's drinking a Packers beer. We converted him into a Packer Backer!" to which I replied "Nope. Washington hops." A couple Hawks fans started laughing while the Packers fans clearly didn't understand my statement, so I said...
Listen, 80% of all the hops in the United States are grown in Washington, so there's a 4 in 5 chance I'm drinking a Washington beer, so STFU!!"
