how much you got in that "kit?" im guessing it would cost a man lots to make a survival kit at the local outdoor shop.
As I've carried/used much of the same gear for years I've lost track of the costs but yes, it would probably exceed $100 if one purchased the contents new or didn't shop wisely.
I've seem some pre-assembled kits that contained quality components but half the fun is testing and assembling your own.
That way, I know what works for ME.
My treks take me into rural Appalachia.
While /shelter/firemaking is very important, carrying a large supply of potable water is not (many small creeks/rivers in my area)) so that "one kit does it all" concept really doesn't do it all depending on one's own gegraphic location.
