I am sorry to hear your lack of C&V-enjoying peers! I'm 34 and I can't fully get away from these things...and I don't wish to. I am spoiled for choice for bikes being here in the NW, and in Seattle in particular, and there are C&V riders younger than 40 around here. But as far as, say, active BF members here or part of other things, it's more like they happen to ride an '80s bike but aren't neck deep in it. If one gets out into the suburbs instead of near downtown where I live, it turns into hybrids and mountain bikes (as commuters!) real fast. I'm a road guy through and through so you're likely never to see me on a MTB. So like you, if I moved out of the city, then the vintage stuff sparse, and even more so for us in this age bracket.

In short, there are a few of us, but we're a bit spread out, even given dense bike-friendly cities. Keep the faith, as some say (at least in this non-spiritual context), we're around here!
