Bought this book back in the mid 70's during the fox boom years. Revolutionized my land trapping. Went from the guy that couldn't catch a fox, to a serious competitor, that rarely missed a fox. After reading this book you will have more knowledge and understanding of land trapping than the vast majority of even some of the best trappers out there. One of the best trouble shooting books any trapper can read. Bud Boda never received the accolades he deserved for this book, even the best guys out there can benefit from it. I highly recommend it.
