For me , bugging out is a poor choice no matter what is coming my way . I'm prepared to B.O. on short notice but I'd need at least 24 hours notice of an impending disaster to make me B.O. Around here even a relatively minor occurance creates major traffic problems . Once when I was out grocery shopping a severe thunder storm blew in . It didn't last long but was severe enough to knock out power for a few minutes [ good thing I had my little flashlight on my key chain ] and knock down some trees and branches . What is usually a 10 minute drive became an hour of traffic jambs and trying to find alternate routes home . If a real disaster hit I don't think me or anyone else would get very far . I'll take my chances bugging in .
