Great idea for discussion. I like Gaye Levy. She and her husband prepped for real. I got good advice on things like a camp cooker, to can outside in cold weather. She talks about everything from arming herself, to appropriate clothing, should you need to get home. I think beginners and intermediates alike will like her canning ideas. On one video, she tells how to make your own brisket.
I also like the Organic Prepper.
All the Prepper sites for seniors are pretty much just common sense stuff and I don't feel that I have learned a thing from any of them. If one of you knows of an exception, I would love to view it.
Modern Survival Blog, is not a video, but a good site with good input, in my opinion.
