I'm getting rumbles via various channels about things nuclear. Chances are these will come to nothing, just as they always have. However, ignoring such things isn't in my nature, and if you're even the slightest bit interested in keeping body and soul together, it shouldn't be in yours.
I'm not recommending going out and going crazy doing last minute prepping. Nothing I'm hearing says that anything is imminent. I do recommend that you read this first, then read over this, and perhaps take a look over the entire ki4u.com web site as an educational excercise.
If you don't have enough food and water for at least a couple of weeks, plus a way to prepare it, this would be a good time to consider that investment. Face it, it's something you can always make use of even if nothing happens.
