I managed to go to one of the smaller (turned out to be not that small) #NoKings protests in a small town in Texas. I wasn't sure if I would be brave enough to go, so I didn't make a sign, but I did carry a US flag. And so did a LOT of other people.
It wasn't nearly as scary as I thought it would be. I was still a bit nervous. (I REALLY don't like crowds.) But I found a spot near the end that wasn't too crowded. It was actually fun. I'm so glad I went.
