There's two kinds of Bug Out's that need to be prepared for....

1) Non-Hostile:
allows one to bug out with a vehicle,
allows one to take the maximum amount of gear, food, and water,
allows one to take the mini/max amount of weapons,
allows one to settle @ a stable destination til time to return home.

2) Hostile:
one can take only what can be carried,
one can only take minimum gear, food, and water,
one can only take the minimum amount of weapons,
one can never stay in one place too long without others knowing that you're in the area.
