Assumptions...
I think everyone needs to prepare for the most realistic scenario that they feel could happen to them.
Some people think a metorite will hit the earth, nuke could go off, and have a cabin in the hills. Some people have a revolver because they work at a convinience store. Armored car driver? Security Guard in bad neighborhood?
I think what you carry will depend on alot of circumstances, ability, and mindset.
Some people are runners, some are fighters..
'Luck favors the prepared'
