survival:the ultimate form of resistance.

[Highlander]

A Bug out bag IS only supposed to be a short term fix, but it doesn't stop you adding a few very light weight items that could last you a lifetime,...

....a couple of wire snares weighs nothing, but could help feed you for months or years.
.....a very good fire striker, these can last for months, a magnifying glass for starting a fire will last forever.
.....a really good knife, doesn't have to be Rambo sized, just good quality
.....and the best book you can find on Wilderness living

I have all these, they weigh very little, but with those few items you could manage in the wilds, providing that you know what to do, and just as importantly you practice the skills

Incidentally the book is `Ultimate guide to Wilderness living` [ Surviving with nothing but your bare hands and what you find in the woods] by John McPherson and Geri McPherson, I highly recommend it
