To be sure it was `settled' long ago, but you have only to drive around the field (say, Virginia road around to rt 62 then back on south st) to see that in between the widely spaced farm houses there are lots of 40's or later looking houses JAMMED in all around. >From what I can tell, it is the `tract housing' folk that mostly raise all of the hue and cry. A note on how noisy small planes are: my wife and I flew down to Connecticut on day to go to some kind of a music festival. We ended up staying lots later than I had expected and it was about 1AM when we started back. As it turns out, I was not night current (although I was IFR current.... sigh..) and so being a reasonable, legal pilot I decided to do the required three stop and gos before I could carry a passenger. I was a little leary about shooting approaches in the middle of the night, but..... my wife reported that even in the climbout from takeoff, my 172 became essentially inaudable when it crossed about 500 feet, and mostly she couldn't detect me by sound again until I was nearly back on the ground zooming right past her. Mostly if you climb out at Vx and get 700 or more feet high before you cross the airport perimeter I think that amything short of a monstrously big airplane is more-than-acceptably quiet. /Bernie
