Every bug out bag should be 100% unique. Sure, there are some basic items that every bug out bag should have (food, lighter, water filter, flashlight, etc.), but you should customize your bag based on where you live, what type of disaster is most likely to occur in your area, and how much weight you can carry over a long distance. Many preppers forget about that last point.

The condition belongs to the geologic age--the great birth and growth of the world, when natural forces ran riot, when the struggle for existence was so savage that no vitality which was not founded in a gigantic form could have even a possibility of survival. That such a time existed, we have evidences in geology, but there only; we can never expect proofs such as this age demands.
