If they're interested at all, the younger shooters' interests lie more with true 'action shooting' - just like they see in their video games and in today's movies.
To see the costumed 350-pound Grandpas and Bubbas, the static stagecoaches, the sameness of the targets and all, doesn't give them something to emulate, much less try.
Plus - shooting 'anything' costs money, whether it's NSSA, CAS, Trapshooting, Zoot Suit, Zombie Shoots, and IPSC - it's all expensive, and the requisite gear can almost be prohibitive.
I don't see that changing anytime soon - no matter how many do-it-yourself articles are written on creation of the clothing, and all.
Unless a young shooter can borrow all his shooting battery from Dad - he's probably spending what little spare money he's got on school, gas and girls - not in that order - and he's not buying weapons, ammunition or hats.
The shooting sports are expensive sports, and time has to be allotted to them in order to prosper (ask any trapshooter) - and in the case of the younger shooters - time is at a premium.
For the most part, the generation shooting C&WAS grew up with Westerns - with their romance and moral lessons and scenery - their offspring didn't have those same messages delivered on a weekly basis, so contending with the 'Zombie Apocalypse' or with the callous events of 'Grand Theft Auto' seem more immediate to them, but as soon as they see 'their' money disappear downrange at a high rate of speed - leaving empty hulls, and nothing more than smoke and echoes - their interests wane.
For them - paintball's more attractive.
The other thing is that in the intervening years since the demise of the oater on TV, shooting sports and guns or gun collecting have become suspect in our non-shooting society - and those who enjoy the them and appreciate the skills can (and are) viewed as outside the norm and worth keeping an eye on.
