I'd like to recommend a great web site: Listening to Katrina. The author weaves his personal Katrina story together with fresh and different survivalist advice in a page-by-page format. He gives advice that I don't believe I'd seen before. As a survivalist for years before the event, he explains the mistakes made and lessons learned.
His section on protecting your wealth is outstanding. For example, if you had a regional disaster and needed to bug out/relocate within 60 seconds, would you have your resume, education certificates and references updated and ready to grab, so that you could start a job elsewhere? I hadn't thought of that.
Neither had he; he tells the sad tale of arriving ahead of everyone else in Houston, immediately opening the classifieds to find the same job he'd been performing for the past 20 years, with a $20k pay increase! He'd be the first in line to apply! Only, since he lacked credentials and references, he wouldn't be able to apply.
WARNING: The Listening to Katrina site has rude language. He also says there's nudity. I hadn't seen it yet, though I am only 1/3rd the way through the pages. Probably bodies from Katrina.
