I'm a "newbie" to Cyburbia. I am NOT a planner but a physician who specializes in pediatrics with a special interest in childhood obesity prevention. I am active in our Regional Community Design Center which is encouraging of walkable and bikeable community design as well as green space for recreation and play. We have an epidemic of obesity that starts early in childhood. I'm interested in public policy change, particularly in the re-design of school settings to encourage healthy eating and exercise. I'd love to hear from anyone who has been involved in the planning and architecture of schools as well as the re-design of some of our older structures.
