I've never given too much thought to bugging out. I have a bunch of stuff here at home and could probably get by for quite a while sheltering in place. Katrina has made me rethink that. Here in the middle of Colorado I really can't imagine a large scale natural disaster that would mandate bugging out. A forest fire for some parts of the state, but I'm suburban.
But if this site has taught me anything, it's to be prepared for anything. A disaster created by man in Denver could very well send a wave of lawlessness my way that I'd want to bug out from.
So I think I'm going to repackage my preparedness stuff into waterproof container buckets we could grab-n-go with if need be. I'm looking at a pile of empty "Scoop Away" kitty litter buckets sitting in the basement (man, those cats sure burn through a lot of that stuff!) I knew there must have been some good reason for keeping those things all along (the buckets, not the cats), and I just now figured out what that reason might be.
