And I did not mean to make a blanket statement, either.
There are still a lot of good folks out there wanting to get involved in this hobby. I suspect that the number are the same as they have been. What skews the perception is that the are a lot more "bARF wannabees" that have unrealistic expectations of what it takes to fly well. Literally, it can take a few hours every weekend for several months to become proficient and and some can not make that committement.
Really, I'm not a curmudgeon...
