Well, because I was curious, I hired a taxi to drive me around downtown on Sunday afternoon. The police presence was there and there really wasn't a way to get close to the protesters unless I wanted to make an afternoon of walking out of it.
And frankly, I had other things (and people!) to do.
I'm in downtown NOW and all is back to normal. But boy, on Sunday afternoon, things were really quiet in certain areas. And many roads were blocked off.
In hindsight, what I've heard if that I got in before a bunch of traffic mess that happened later in the day.
