Marlin sums it up pretty good and many may loath any such organization, but in the end it comes down to a personal decision and how one feels about the bigger picture and the benefits that result for the sport, birds and habitat, etc. As a professional (landscape architect and golf architect) I belong to society organizations and I do so with certain caution/trepidation, but nonetheless I know the overall benefit overrides my personal issues and I am okay with that.
Good luck with your decison Shad.
