Sandy taught important lessons. Maybe not every student who encountered her teaching has learned as much as she offered, but few went home without a bit more wisdom.
There are several of Sandy’s students — especially after a couple of beers — who will explain the difference between a local emergency and a regional disaster. Some will admit that after Sandy they see how a disaster, especially in a dense urban context, can detonate the whole web of modern interdependencies. Just a few more two years ago and very bad might have become catastrophic.
A tough teacher in the school of hard knocks. But some — enough? — are better prepared for the worse still to come.
