I agree with Post #2 and would like to add that all communities have resources at their fingertips. In the case of a disaster, most communities have and do come together to strengthen and reinforce their disaster-fighting capabilities. So knowing what resources they have to begin with can be achieved by having an audit of available response teams. Then, they could opt in to participation in a local, state, or national pool of resources should the need for a greater crisis arise.
There are many local, state, and national websites that give counsel, guidance, and additional information. We're all familiar with FEMA (the Federal Emergency Management Agency). They have an excellent website that not only covers national disasters, but has and will help with local and state emergencies. Many of their departments will give guidance to individuals and communities needing help. And let's not overlook the states' websites. Most, if not all, have departments that address emergency response and available resources. Find your local state's website and look at all the possibilities for getting information and assistance.
