@pachi: I was there in 2016~ I've gone every year since 2010. What if we happened to pass by each other and we didn't even know xD
The subway is dirty, I wish it was cleaner but at least it safely gets you to where you want to go which didn't use to be the case. lol
I actually really like DC. The first time I was ever there was cause of Otakon, they moved there in 2017. I fell in love with the city. The metro is way cleaner, I love the museums and the architecture of the buildings.
Not this year, cause Otakon is cancelled, but maybe you should come to an Otakon in the future and then stay a few days after for the free museums?
