Dr. Prepper, a/k/a James Talmadge Stevens, is a really big deal in the prepping world. He wrote THE non-fiction book on survival, Making the Best of Basics. It’s sold 800,000 copies (not a typo).
His radio and podcast network, the Preparedness Radio Network, is huge. PRN has lots of good shows on it; consider listening to them.
He and I had a great conversation about prepping and the 299 Days book series. Here’s the interview. I highly recommend it.
