Three of the former courses at New Orleans' City Park have been out to pasture since the storm. As such they're very much part of a public park, and I've walked them a few times. Unfortunately they're not kept for anything really, so no one walks them or uses the space at all. Some of the land will be used for the new course and related facilities, but I don't think all of it. I hope that at least any unused land sees more activity than it does currently.
