Hopefully different where you are but here most people have no sense at all of what is coming or preparing for even minimal disruption. For example, when I asked neighbors about water storage(where we are no power means no water)they acted as if I was a nutjob who needed more medication. For even thinking about the most obvious basic necessity!! In spite of just being subjected to Hurricane Sandy!!
So the best thing might be to try and open as many eyes as possible, get people to at least consider their situation, because if everyone is so totally unprepared, we are all going to burn.
And ultimately realize that if this is the response you get, you need different neighbors.
