Do you know morse code?
Here where I live, electricity goes out during big storms. Along with electricity goes the phone system. Me and my friend live across the way and we learned how to do morse code during the last storm, but using Flashlights. It is pretty cool once you get the hang of it. Of course, it is not such a bad skill to have, knowing morse code. You never know when you may need to use your morse code, using flashlights. I think I have seen enough hollywood films where those basic skill sets come to play during an emergency. Hey, I may be that guy that saves the town. You never know!
