Yes, they are. I am a Tri-Ess member (associate status, now - TS are not accepted as full members), in one of the few remaining chapters. As I understand it, chapter activity around the country waxes and wanes, but has been generally on the wane for many years now. It is fair to say that the organization is a shadow of it's former self. Virtually all of the active members are older than myself, and I'm no spring chicken. The few new, younger members, that have come along since I joined a few years ago seem to drift off quickly. It seems clear that the community no longer has need of a safe, albeit almost cloistered environment in which to cross-dress. The activity hasn't been illegal here in Houston for a few years now (going on 40, actually), and younger people just don't seem to need that "support".
I'm still active, because it offers a way for me to give back, but honestly, I view the decline of such organizations as a good thing; a sign that the TG community is accepted enough that we don't have to hide anymore.
