On NPR yesterday morning, they reported that areas hit by Hurricane Sandy had buses running again, but it would be a while before rail service resumed. After a disaster, being able to drive around obstacles (which cars can, but trains cannot) is a significant advantage.
They also reported that on Long Island many people were staying in their homes, despite having no power or water, so they could protect them from looters. It’s a pity that New York law has made sure that most of those people protecting their homes are unarmed. Natural disasters show the folly of relying completely on the government to protect your property.
