Maybe so, but it looked sunny and bright, and not everyone was bundled up like Eskimos.
In my view, it wasn't the weather that kept people away, but the fear of violence.
I heard way too many 'allies' warning people to "keep your head on a swivel", and other statements, in the days and weeks leading up to the event.
It was in the 20’s with a constant 15+ MPH wind. My face is still red and burned.
