If your gun club is not doing well there are two things working to make it flounder.
Every club has a reputation, good, mediocre or bad.
The first step to resolve any problem is to admit a problem exists. Boys who have been members since time began, but the new members. That's the cliche forming. The ripple effect is powerful and it will silently damage the club's reputation over time. Since it takes years to ruin a club's reputation, it'll require years to absolve its sins.
