Lots of "squadrons" very few airplanes and pilots. Its like the GA state militia for airplane nuts. Its been dying for decades now as there is next to no Federal/state support and the numbers of GA (General Aviation) pilot/owners with the time and money (and health) to volunteer for it has dwindled.
It is good for the kids, but it is extremely frustrating for adults.
I was in it @20 years ago for a couple of years. I was a commercial, multi, instrument rated pilot at the time. I just wanted to volunteer my services and maybe fly a search or two if needed and take the kids up a few times.
In two years, I flew exactly 0 of those missions. Maybe I was in a bad area-but it sure seemed like a good ol' boy club (at least for the adults.) It was impossible to get a check out for anything other than just renting the plane. Seemed like if your didn't live in PC and work for a certain airline, there was no chance of getting to do any of the fun stuff.
I got pissed and never went back. I can think of 7 or 8 other pilots who got pissed and quit with similar experiences. We were all trying to volunteer our time. And we all just got treated like ****.
-But even after all that, I would recommend the organization to anyone who has kids interested in flying. They get to do and see some cool stuff.
