What are your favorite research materials? It's never too early to research for this upcoming season and I am learning a lot. Anyone ever use this out-of-print classic? I have found it to be dead on accurate for 3 out of 4 animals I am researching, but it is way outdated when it comes to some southern sheep areas. Overall, it is an amazing piece of literature that I hope everyone gets to look at sometime. Unbelievable detail on habitat areas.
