It is delusional to think the chances are good of a neighbor just looking up the map and joining in. Geeks need to talk to people in real life, especially in their neighborhood. Team up with at least one other person. Use word of mouth. That is effective change.
Unfortunately I live in a remote area with non-tech people who are not conservative enough to be preppers. I will still run it past them though.

A grumpy curmudgeon like me? You must be crazy!
