Emergency / Survival Gear. After I found this website, all I ever looked for / bought online was flashlights. But I've branched out to Emergency / Survival Gear. Go to any website that talks about emergency prep kits and a flashlight is pretty much always on the list of must have items. I figured I might as well get the other items on the list and be prepared for more emergency situations that come up.
What do you consider to be the most important piece of survival gear that is worth collecting?
