So there was a protest. According to the overall organizer website, Savannah had one scheduled. We were to meet at the corner of Bull Street and Broughton Street and march to Johnson Square.
I didn't find out about this until an hour before. Also it was forecast to rain all day. But I went to check it out. Unfortunately, I was the only one there as far as I could tell:
After about half an hour of walking back and forth by myself (without the yelling or sign waving; I had no sign), I gave up and went home. It started raining heavily about five minutes after I was back in my car.
Fortunately for the rest of the nation, it looks like a lot of other cities had successful turnouts. Next time, whoever's in charge in Savannah (if there is anyone in charge, and I'm guessing there isn't) needs to give louder and earlier notice about such things.
Meanwhile, it would probably be more effective to bring the issue to the federal level and get a SCOTUS ruling for the entire nation instead of doing it piecemeal like this, one state at a time.
