Here is the first site I found when I first started looking at building a serious survival kit.
www.m4040.com/Survival/Survival%20Kit.htmEventually I found Equipped to Survive and the Pocket Survival Pak but the basic contents are actually very similar. The more kits you look at the more similarities you will see, but you will also see there are some differences when you look outside the ETS community. That is not a bad thing. In my college days (I'm not telling how long ago that has been) my professors used to say that the college preferred to hire teachers with degrees from other colleges. Not that they didn't think teachers from their own college were not well trained, but they didn't want to perpetuate the same lines of thinking. Outside the box thinking can only come when you look outside your own box.
