The beach or the park succeeds based on the willingness of everyone who enters to uphold commonly accepted expectations. Maintenance of the space becomes reflexive, a civic habit that is self-reinforcing: When you enter a beautiful space, you are inclined to keep it beautiful, no public shaming required. Unfortunately, the inverse is also true. If it isn’t a beautiful space, then most people aren’t inclined to keep it beautiful. And when these conditions begin to prevail, public spaces fail, often precipitously. – Washington Post
