I think I can speak for CRAFM when I say that unless a dozen or so people/members come forward with plans and proposals for IDPA matches and practice, then it will never take-off.
At pretty much every club, it is the volunteers that organize and run the matches, whether it be IPSC, IDPA, PPC or any other discipline. The clubs are simply locations providing the shooting space.
If you have an interest in IDPA, recruit like-minded individuals and propose your ideas to your local clubs. It's the only way. The PPC guys did it at CRAFM, and in the span of a few months, we became approved for PPC shooting by completely re-designing our baffle systems to allow for prone shooting. Ask and ye shall receive (if the demand, and effort, is there).
