Theres a great book that you can get thats called "ELK TALK" writtin by Don Laubach and Mark Henckel, with introduction by Jim Zumbo, If your new tto the sport this book will be very usefull for you. Or even keep seasoned hunters with ideas and thoughts not to forget. But this book isn't just about calling in elk it aslo talks about an elks life from birth to death. I found mine at GI Joes, for about 17 bucks. Archery is a great sport, I sold my last rifle just a couple days ago. Good luck. Mike
