One thing most people never think about is information maps.
I use and have a collection of maps with anything i think may help me survive marked on them
Forest Service fire camps would be a good source of hand tools do you know where they are near you.
Military bases have real good stuff up to armored vehicles and using the base phone book can tell you where things are on the base.
If the military has fallen apart or no longer exists these bases can be a supply point.
Google earth and maps gives you a way to print out maps of a area you may want to use as a survival area.
Then in a pre survival camping or week end trips you can explore the area and mark the locations of things you find for the day SHTF.
I have a map collection that covers over 500 miles
Clean water sources i have checked and found the water source for 100s of campgrounds most are spring water from a covered source that needs no
Solar panels on building, road signs, ECT. that in a SHTF are there for the taking.
In a SHTF do you know where to find hazmat equipment, heavy equipment, your national guard armory.
If you need weapons your local police department may have 100s in there evidence storage. If things have gotten so bad that the cops have disappeared
all you have to have is the tools to open there storage. same with national guard armories and gun stores. home owner gun safes.
These tools can be found at your local fire department. you would be suprised at what you can take apart with a K12 saw and the jaws of life tools
found at most fire departments.
Many rural and small town fire department have food supplies MREs ECT for disasters or wildland fires that take days to fight.
Many have amounts large enough for family members to shelter at the fire department in disasters.
Some rural and small town fire departments also are the local civil defence headquarters under the old national relocation plans.
I know much of this because i was a volunteer firefighter in a small town.
Saving all this information may save your life.
Google earth and maps can be printed out on your printer.
The things you find can be marked with numbers and descriptions and GPS coordinates on the back of these maps.
They can then be made waterproof with clear spray lacquer or plastic spray and put in a thin binder.
