If you are prepared, your home should be your first line of "defense" in a survival, EOTHAWKI, situation. Store what you can, where you can and know where things are. An offsite storage facility, located within walking distance, can also be used.
I don't plan on bugging out if I can hunker down. I know how much I can carry, versus how much is in my house and garage.
The key is prior planning.
