Let's see.... Had none prior to 911; now I have plans and equippment. I have gas masks for the whole family, carry two altiods tins, have a radiometer, have a 4X4 with a BOB, got my EMT basic lisence, got my HAM lisence and a decent handy-talkie with receive coverage on all commercial, police and weather channels as well as transmit on 2 meter 1.25 meter and 440 cm wavelengths, more flashlights than my wife can believe and decent woolen clothing for whatever eventuality, enhanced my knife collection quite a lot and got back into shape for mountain hiking (my favorite sport anyway). <br><br>Nope, I guess it didn't make much difference.
