Once in ever so seldom I go to a picnic spot off the end of the runway at K---. What impresses me is the number of 20-something females who show up with their small children to watch the planes.
They probably aren't just waiting for the phone call to pick up daddy at the airport since the access road is one-way away from the airport. It would take negotiating a a maze of raods to get back.
Spotters, nerds, geeks, anoraks? Not really, but they must have some aviation interest.
