It might be a good idea to find out who your local HAM operators are, and become acquainted.

If you really do need to get a message out of the area, they may be willing to help you. Or not. If your problem is relatively local, siphon a gallon or two of gas out of your car (or someone else's), and pay them a cautious visit. If they have a generator, they may be able and willing. Have your contacts (one or two, not twenty) and their phone numbers written down, as well as the message. Make the deal, hand them the note, hand them the gas, say 'thank you' and leave.

If there's reasonable chance that they will do as you requested, realize that they aren't going to want you in their home, hanging over their shoulder and waiting for them to actually make the contact.
