There is a man on YouTube (okay there are hundreds of men - and women - on YouTube) who has dedicated his life to Preparedness efforts. His "handle" is SouthernPrepper1 and his information is fantastic!!
Here's some general information on his profile:
"I am married and the father of 2 great teenagers. Retired army infantry, prepper, survivalist, homesteader and most important a Christian. I am interested in helping people survive the hard times that are coming. I have a very supportive wife that lets me prepare for the disaster that is heading our way. My only goal for this channel is to help people."
Here's my DISCLAIMER: I have not watched all of his videos, but what I have seen I find to be appropriate and extremely useful. Take a look at his channel if you like.
You can find his videos here:
