Hasn't the BBBC always carried a strong ODNR connection?.....doubtful that the late 50s would have seen individuals themselves coming up with the idea for such a trophy-focused promotional organization given deer populations at the time....just seeing or shooting one was enough for most.
The state connection alone, when noting a tad bit plus ODNR dislike and dislike of ODNR deer management plans today, would seem to play into hunters and shooters preferring other more modern or less state affiliated deer organizations.
Recently talked with a friend who stated his father and buddies walked a couple of miles to see a deer track around 1960 in Washington County. Even I can recall Saturdays spent looking during an October, 1960 in Washington and Monroe....that action for an 8 year old was fun and much of what led to friendly, non-competitive groups of deer hunters, the dreaded drives and and a general good feeling for the coming of ....deer gun season.
That interest, that keenness, that hope, that comaraderie probably boomed the BBBC for a good spell.....but, a lot changes in people over 60-70 years when a lot changes in a resource and in many of those who see a resource as defining themselves.
Good luck to the BBBC....tradition and first should mean something, regardless.
