Yet another fascinating blog entry from Preparedness Pro about communications in an emergency situation. When all hell breaks loose, it may not break loose where you live, it may break loose where someone you love lives. How can you keep in touch?
Kellene makes a number of very intelligent recommendations including having a wireline phone with corded phone for when the power goes out, skype (which can be used with a cell phone) for emergencies away, and a number of other options for long-term outages when wireline phones are not an option. How about becoming a Ham radio operator and get plugged into an alternate network of news on the ground. Learn shorthand, and/or Sign Language. There was an episode of Star Trek where Sign Language was used in battle when regular communications were out.
It strikes me that if you have a group of like-minded preppers and you all learned an abbreviated set of signs to use in emergencies when quiet is necessary, that would be a very good thing. You can even come up with signs of your own.
