(Historical Notes: I’m still not sure what exactly was going on with this mess.  On the one had, the DC area in general is sort of infamous for having bad reception because there’s so many places where people are paranoid about spy devices.  No, seriously, that’s a thing.  But on the other hand, the National Harbor is pretty far out from DC, and I can’t imagine there’s any valuable government secrets that need protecting in the back of Ballroom C or whatever.  And surely, the answer can’t just be that my own phone was starting to crap out on me.  Don’t be ridiculous.  Also, I imagine The Great God of WiFi hanging out with the Tetris God.)
