I always get a kick out of the urban dweller who thinks they will escape mayhem by rushing out to the wilderness and waiting it out. As if the other Like the million other people in the city are just going to stay put. Bugging In is the most realistic method of waiting out a disaster. That being said... The most likely scenario where one would have to leave would be a natural disaster ( flood, fire, earthquake) so preparing for that is definitely imperative. Prepping your own home is always the best bet.
Correction :" Bugging in is the most realistic method of waiting out a disaster..", especially if you have nowhere else to go,
provided that you have already prepped and have (#1)water,(#2)food, (#3) a means to defend , (#4) heat/energy/cook.
Some of the most prepared (campers) I know have already found out through 'trial and error', and have learned more from what they forgot to include in their supplies.
You learn faster and quicker through your errors than you ever will from suggestions or instructions.
Practice makes perfect !
