Part of my personal landscape, unfortunately, is the zoo overflow parking on the Greensward, the one big picnic field in Overton Park. Every nice weekend, plus a good many other days, the zoo parks hundreds of cars right on the most used part of the park. This weekend, they not only parked as usual, but they crossed the "line of demarcation" which they are not supposed to cross -- marked by their own workers, ironically, in bright orange cones. They're supposed to leave the rest of the field for people (having completely spoiled the view and restful nature of it with their hulking SUV's). Saturday they blatantly crossed the line. I'm not doing a lot of overt social commentary in this series, but this is one issue that continues to burn at me.
