There is a new concept out there or debate on in a last minute dash to safety from your home or any situation that leaves you without the creature comforts of home to always have a Grab and Go Pack or Bag. I suggest the basics first, Food-Water-Firestarter-knife. You cant take more than you can carry so make it count. Second Toilet tissue 1 roll at least, at least one change of clothes, flashlight with extra batteries, a small am/fm shortwave weather radio, a few garbage bags to keep your belongings dry, some parachute chord for tying up a temporary shelter. If you have a big ruck sack with a metal frame you could really add more items than this but keep it small its grab and go not tug and pull.
