and I try to keep a small supply of similar necessary items in each vehicle just for the day when you are stuck in traffic or a snow bank in town...

it is expensive though to plan for something in all locations/vehicles. I've got a small survival kit at each work office and the wifes too: light, knife, food and drink items, dust mask and such... watching the 911 stuff a while ago on TV made me think that I should have a few of these items with me at work.

Some people laugh at me and have said... "heck I'm just going home if it's bad..." but what if you can't get there! Big crack in the earth or some other disease/chemical etc. (i work downtown)
