Check your bylaws, JEB. Do NOT just let the current crop of leadership run roughshod over the club! By knowing the bylaws inside and out, you can create a strategy for dealing with an obstinate President/Board of Directors. Typically, something like this is handled in Robert's Rules of Order. Many states require bylaws of organizations to use Roberts Rules.
Is there anything in the club bylaws limiting what motions may be brought to a vote? Or even when they can be brought to the meetings? Usually this will be in the portion of the meeting under New Business. You would basically stand up and say something to the effect that you are moving that the club limit equipment to primitive, traditional, and compound archery, but specifically excluding crossbows. Once a motion has been brought, it requires a second, opportunity for discussion, and a vote. Someone on the Board of Directors can then call the vote to be tabled until a later meeting. But that is only a delaying tactic, once a motion is called and seconded, eventually it MUST be voted on. Our bylaws require a vote within 12 months of any and all tabled motions, they may NOT languish, or be "hoghoused".
Secondly, find out who your insurance carrier is. Your club must have insurance, and it might NOT cover crossbows, depending on how the policy is written. A phone call to the insurer will answer that question. Our insurance at the Black Hills Raptor Center is written quite narrowly on what it will cover and what it will NOT cover. By writing a very restricted and narrow insurance policy, we cut premiums in half by showing the carrier that we knew what was safe, what was not, and how we could protect ourselves.
Canvas the Board of Directors, what are their opinions on the issue? The president does not dictate the policy....in fact, the president is there only to preside over meetings. He gets one vote as a member. President does not mean Dictator!
Sometimes it is in your favor when the general membership fails to show for a meeting. Allows you to "pack" the vote in your favor! I did this several times with the presidency of our local muzzleloaders club. Also guaranteed I was not re-elected the following year both times, though! But hey, cost of progress!
