Anyway, it was very weird biking down that street with no cars. It took me a while to get it into my head that I could actually use the whole road, not just the bike lane.
The most striking part was how quiet it was, even though there were 10x as many people there as normal -- and how it didn't smell at all like exhaust. I didn't expect to notice that as much as I did, but yes, roads without cars on them don't stink! It's like when your ears finally pop and you can hear again. You don't notice it until it's gone.
It was even more noticable at 1PM when they opened the floodgates and let the noise and stink back in. Sad.
