I was there for the first rally which is in the video, I'm just out of view on the left. my estimate for that day was 3-4,000 people. C4L put the number at 5,000. Not a bad turn-out for 3 days notice.
I missed the rally yesterday, which I think was about 2,000 people because I don't think the word got out very much. I didn't even know myself until I saw somebody posting on FB!
The 28th should be big. Word spread early about it and the state legislators will be there that day...so I expect to see a very large turn out. I'm hoping for 10,000+
