Urban Prepping [http://www.urbanprepping.com/]
This is a fantastic and well done site, lots of free reference material that is well organized and presented. Note also that the owner of the site is not trying to sell you anything. The “for-profit” bent of so many prepper sites is, IMO, a bit off-putting and runs the risk of creating an appearance of bias and interest in creating panic. Kudos to UrbanPrepping.com. GE.
