Bugging out is not camping.
Bugging in is not homesteading.
Survival gear and skills is not the same as SHTF gear and skills.
The difference is not self sufficiency. Lots of people go on multi-week (or month) hiking trips through wilderness or live completely off their own...
What is every ones opinion on bug out vs. bug in for urban, suburban and rural?
For me I would say bug out for urban. With suburban I think it depends on how defensible your location is. Rural I would definitely say bug in
