Okay, if that is what you mean by a bugout bag... I think many ordinary folks just need a 72 hour bag with basic essentials to get them through until they can get more permanent help. Your right, bugging out of society as a whole isn't really practical for most people.

As for big storms- ideally, yeah, but it seems that a lot of folks try to ride it out, it ends up being worse than they expected, they get flooded out, and now have to be evacuated in a hurry.
