The best place for an emergency bag is a place that is easy to access. You should be able to grab the bag and go at a moment’s notice. Don’t bury it under a lot of other stuff in a hard-to-reach corner of the basement or attic. A closet, preferably one near an entry or exit is preferable for making a hasty retreat out the door. It’s not a bad idea to keep a smaller bag of supplies in an easy to reach spot in your vehicle too.
