ADDED: On this overcast day, there were few people in the gardens. An artist painting a tree. Some older couples wandering and pointing things out to each other. Bunches of schoolkids, led by teachers. One kid asked if it was "wabbit season." Another kid wanted to know how they were going to get to wherever it was they were going. The teacher said: "We're going to use those things attached to your legs. We're going to move them back and forth. We're going to walk."
