This is good information, and in these troubled times it is something that many urban dwellers should give more than casual consideration to, but what disturbs me the most about all of these doo-dads and gadgets is the COST. Sure, I value my life (some days more than others), but am I going to plunk down $200 or more for an escape hood I may never need? Not likely, given my present financial state. I know there is the "what's your life worth?" argument, and I agree with it to an extent. But for most of us, other than minimal, low cost or improvised gear, spending $500-$2,000 on a bug-out bag is not only not practical, it's just plain impossible. Why do you think most of my recommendations on where to get survival stuff are check the local K-mart or Wal-mart? <img src="images/graemlins/crazy.gif" alt="" />That is one of the things I truly value about the Survival Forum - a lot of people on here have great ideas about how to do/make/remodel things so that survival is not only practical, but also cost-effective for the rest of us.
