NZClaybuster, I was visiting the area and had some spare time. I am a member of my local club for skeet but also shoot as a non-member of 3 different sporting clays clubs that are about 1 hour drive from me. The only reason I am not a member of these clubs beside the 1 hour drive is that they shoot with same days as skeet at my club, 15 minute drive.
All the clubs in my area welcome walk-ons for trap and skeet (if they offer skeet). How else do you attract new members? No one joins a golf club if they have never played golf before
