Ludwig Wittgenstein

Though builders may build, in the main they follow the plans of architects. Teachers teach, but they must have a text. Politicians govern, but only upon the flow of commentary that raises them up or casts them down.

The best way to get a sense of what kinds of emergencies might present themselves in your community is by contacting local chapters of the American Red Cross or offices of emergency management in the region or state. Most large cities will have their own offices of emergency management.
