A must-read book for anyone who is trying to "Prepare Accordingly" - check out Fernando "Ferfal" Aquirre, "The Modern Survival Manual - Surviving the Economic Collapse".
This is his first hand account of surviving the Argentina hyperinflation of about 10 years ago. Lots of stuff in there about security, precious metals, etc. His book seems like the most likely scenario of any I have read.
He also has a web site, ferfal.com or themodernsurvivalist.com. Again, I am not at all affiliated with him.
