We happened to be on Castro street today when they closed it off for some sort of festival. Within 20 minutes of the street being closed to cars, people started walking in the street instead of using the sidewalk. Within an hour, there were dozens of kids playing chase in the middle of Castro, and having a fabulous time. It was amazing to me how quickly the street became a promenade, and how much the kids enjoyed the freedom of not having to worry about cars. The cops patrolling on bicycles also seemed to enjoy themselves. I wonder if we could have more walking streets. I think kids would enjoy it, and adults might too.
