Two groups of redditors met on the highway on the way to the rally

Context As my friends and I make our way down to DC, we see a van traveling on our right. The guy driving grins at us. At the time, we had no idea why. So the next time we were parallel, we all smiled back in unison in a somewhat creepy way. The third time we became parallel the driver in the van pushed a make-shift sign up against his window saying, "RALLLY FOR FEAR/SANITY???" Immediately upon seeing it all of us in my car busted out saying things like "YES!" Next he held up a sign saying "Check r/politics!" We then made our way to meet up with these fine fellow redditors. Apparently my bumber stickers and laptop usage was a dead giveaway. End result!
