This apartment complex is across the street from the Washington Nationals ballpark in DC. And since it opened in 2013, residents have been putting up banners to support the team.... or even another team they like.
But this is 2017, and it seems we just can't leave well enough alone. Seems everything gets political. And that's why the owners of the apartment complex have decided to enforce a ban all patio banners. You can see why in this photo from Twitter. Yes, there were still people putting up baseball signs; but politics had become a big talking point in the patio banner wars. And they were really wars of words. Look at the Trump banner, and the (admittedly clever) "Nope" sign with an arrow pointing up below it.
People, stop ruining all the fun!
