Seems like it's on the wane here. I had been kind of interested in getting into it 15-20 years back, but never did. I'm not even sure if they do shoots around here anymore. I haven't seen them advertised at any of my local-ish LGS in years.

A lot of the bigger/online shooting retailers that used to carry a lot of CAS stuff haven't in quite a few years now, which is also a pretty fair indicator, imo.
