Free: Contests & Raffles.
I agree on the cost issue. I have a bear recurve, a Kodiak I believe that I got at a gun show for $60. It's a 60 pound draw and can only shoot the same as when it was new. It has to be at least 40-50 years old.Another great book is Fred Bears Field Notes. Some of his hunts from all over the world.
There guys who still use bows that were made back in the 50's and 60's.
