I dont know where you live, but, Salsa and WCS, are not remotely populated by the younger generation ( States side, WCS and Salsa.. and salsa in the UK ) .

Of course, we need to define " younger ".. The locations I have taught and danced in for many yrs, have, for e.g.in some Southern US States a dominant older clientele, and yes, there are clubs that attract the younger crowd .

WCS seems populated by a 25 - 50 age group from my past experience.
