Hundreds of people showed up for the first day. I estimate that at least 50 were planning on staying in tents. The space in front of city hall actually has an amphitheater and it's perfect for general assemblies.
A lot of people worked hard to make it happen, and it was an amazing and positive event. As far as I can tell from Twitter, people are still there, and a city council member is staying the night.
This is the largest "first day" I've seen yet. Not bad for a Monday in the rain.
