I had tremendous four days in Missoula, Montana attending the Boone and Crockett Measurer's class. We were instructed, in great detail, in the proper methods of scoring 38 categories of North American big game. Learning to score was a highlight, but it certainly wasn't the emphasis of the intense pow-wow. A branch of B&C keeps records of big game horn, antler, skull and tusk measurements, but the clubs primary purpose and influence has been in habitat management and conservation of big game as a renewable resource. B&C is the oldest hunting/conservation organization in North America - the big brother of conservation.
