Saying a chain saw is the most important tool so you can clear streets/roads for other people to travel (it said something like that), is ridiculous.
And, don't upset anyone when you talk about an emergency - it might turn them off or scare them. Hogwash.
Search out people who need help and give it to them. I guess that means your water and food.
That whole thing is simplistic and not realistic. No wonder FEMA went with that article. It was confusing. Somewhere it spoke of self reliance and that was the best two words in there.
I would say if you let FEMA know anything about you and your preparedness if they show up on the scene, you are nuts.
some say clearing the streets others say creating choke points and firing lanes, i wouldnt say its the most important, but its not a bad thing to have
