Why Carry a 72 Hours Survival Kit? (also known as "Get Home Bags" - GOOD BOBs <Get Out Of Dodge or Bug-Out-Bags> are usually larger and more inclusive.)
Most Disaster Scenarios are over in seconds, minutes or hours but Help may not reach you for 2-3 days.
MY GREATEST FEAR: Forget wind storms, fires, terrorism, etc for the moment. NASA (our space agency) says Solar Storms are strongly possible. On September 1–2, 1859, the largest recorded solar storm occurred. The flares set fire to telegraph lines and office in the US and Europe. Do you know anything with wiring?
Imagine - IF a Super Solar Flare (Mass Coronal Ejection) occurs, the first wave slams into our communications satellites. All cellphones and the entire Banking ATM system shuts down. When the solar flare strikes Earth, the electrical wave would overwhelm and burn out major sections of our electrical grids. Unprotected motors would burn out. IF cars were drivable, roads would be restricted to Military and Emergency Vehicles Only. How Far Might You Have to Walk to Get Home? or, to reach children, family or friends?
Step 1: The Basics of a Great 72 Hour Survival Kit or Bug Out Bag
The size of your backpack should be based on what you can realistically carry - At A Minimum - to survive 72 hours or more.
The pictures below show my current two favorites. You can buy backpacks with Water Reservoirs. Daily I carry the 72 hour kit on the left with the two external pockets for water. One is full and the other is a "filtered water bottle" for a dip-and-drink scenario. <<It's ALWAYS best to boil water.>>
The larger, green 72 Survival Kit is called an Alice Bag and they come in various sizes. It has a light metal frame which supports your lower back. It's famous in the US military for its large, deep pockets.
