I found it fascinating and I ordered both of his books, The Forgotten Skills of Self-Suffidiency and Backyard Winter Gardening, from amazon. I have actually attended a class that Caleb taught at Honeyville, and loved listening to him speak, but I never purchased his books. The books are very interesting from a historical standpoint, but the information on gardening is why I bought them both.
Just like in the video above, I really want to try using cold boxes to have fresh greens all winter long. The books are full of colorful photographs and tons of information on gardening, chickens, history of the pioneers in Utah, etc. There are even a few recipes included. I felt these books were good enough for me to share with all of you! I highly recommend adding both books to your preparedness library.
