I did not grow up on westerns, only cowboys I saw in my childhood were in a form of satire showing the bad and the scary President Reagan wearing cowboy garb and a top hat in Soviet newspapers
I had no idea CAS existed until February this year when bougth an Interarms Virginian Dragoon in a deal too good to pass . Soon I got too bored punching holes in the paper and started looking what I could do that was fun with it. As soon I saw first SASS youtube video I was hooked... So maybe a generation does not need to grow up on westerns to partake in CAS if it would find something they like there?
And a discipline that attracts younger, more able bodied people, and (GASP) relaxed costuming requirements might be that? I know, Spirit of the Game is important, and it is designed to be what it is on purpose, and I do my best and enjoy dressing up but when I talk to my friends who shoot - they might be more inclined to participate if there was more challenge, more physical rigor, less "old school".... W3G looks like just what they might like!
