There are two things that are always true in GA:
1. Hangar space is scarce. Not because GA is booming, but because friends and cronies of the local powers that be are allowed to fill hangars with junk instead of airplanes.
2. CFIs will always be in short supply. Often (as in my neck of the woods) it's because of a shortage of rental planes in which to train. Sometimes it's because the only CFIs left are the ones who refused to give up. All the others have thrown in the towel.
If you want to take a true measure of the state of GA, all you need to do is Google the number of aircraft built in 1973 and compare it to 2013. The collapse has been staggering.
Another true measure of GA is to do what we do: Fly to as many GA airports as possible. You will still meet plenty of nice people, but too often you will find an FBO office that looks like a neutron bomb was detonated 25 miles away. Everything is in perfect order, exactly the way it was when the last WWII guy walked out the door in 1992.
The old 1989 Flying magazines, the yellow business cards on the bulletin board (with the Cherokee 140 for sale for $21K, and no takers), the orange plastic chairs, the old shiny fabric brown couch, ALL are exactly the way they left it -- and no one has been back since.
I have personally flown into dozens of such airports, in Iowa and Texas, in the last 15 years. It makes me want to cry, partially because I really miss those WWII guys, but also because these places so graphically illustrate our complete failure to attract new generations to general aviation.
I've done everything I know how to do, from building aviation themed hotels, to kick starting aviation exhibits at children's museums, to mentoring three people from zero to Private. All have been fun, but to little avail WRT the overall state of GA.
