(Hey, we never thought of that!) He showed them plans for domed cities, cities with no basements, no foundations. Cities that could be moved in a minute. Portable cities. Portable towns. He said; Think of it as camping out. Think of it as one big tent. He said: Think of it as The Big Top ... spinning ... lightweight ... portable. He said: Think of it as The Big Top. Spinning ...
