The Traditional Bowhunters Handbook is an excellent resource for any traditional archer. I refer to mine all the time, and even lend it to friends who are just getting started. Very useful. And Campfire Reflections gets re-read on a regular basis. If TJ puts out another book, I’ll happily add it to my archery library.
I’ve also got two of Don’s books, Longbows in the Far North and Longbow Country, and I’ve got my eye on Have Bow, Will Travel. Don’s writing is absolutely amazing. If you’re looking for a good addition to your outdoor library, you can’t go wrong with Don’s books.
