Hi all,

I've found many of the GNIS-imported airports in my area (central PA)  
to be abandoned. As Lars already mentioned, oftentimes this is easy to  
determine from aerial imagery. The information at http://members.tripod.com/airfields_freeman/ 
  has also proved to be very useful, with lots of pictures and  
historic aerial imagery.

I would be very much in favor of having a three-level classification  
scheme as outlined by Zeke. +1!
