Alex, no matter where my wife & I travel too, she hits the local value village looking for "period" clothing. I think that can be said for any experienced shooter. We initially buy our clothes at Lamellae's (sp) or Wild West Mercantile and quickly discover the importance of second hand clothing stores. I have lost count of how many times over the years I have outfitted new shooters who want to shoot their first match with leather, rifles, pistols, shotguns and ammunition, the least a new shooter can contribute is paying lip service to the minimal clothing standard. If the shooter develops enough interest after this first experience, they will no doubt understand that there will be a cost involved.
As for new clubs, my wife and I discovered a new group about 90 minutes south of us, earlier this year that had been going for a couple of years. They are a group of 8, that don't apparently believe in advertising themselves, they have built 4-5 really nice frontages, got steel in various sizes, placed it at various distances from 15 yds to 47 yds, when asked about rules, I was told "we don't follow anyone's rules" and apparently after a couple of years of shooting I was the first to bring a timer with me. One of their shooters told me that in the future that they hope to hold a match with 40+ shooters. Its my opinion that the only cowboy shooters that are willing to travel to a match repeatedly are SASS members and that paying lip service to the rule book will bring more shooters out. Which I pointed out, sadly I feel I have happened upon deaf ears.
