I've got copies of my important paperwork folded in a ziploc bag with my BOB, but I have yet to do an actual emergency binder.
I need to do this when I get some time. I want to do one that has not just personal info, but also some general emergency preparedness info and technical info.
All that stuff which I always forget or don't have memorized. How much bleach for water purification, the entire morse code, useful mathematical formulas, useful chemicals, general settings for electrical and gas welding, radio bands/frequencies, local maps and charts, ect, ect.
