Martin,

One idea I've had, but never implemented, was to scale the grass area around a 
cutout by the size of the cutout.  Some smaller fields, like UT40, have a 
grass area many times bigger than the airport itself.  The real version of 
this airport (to the extent we can even call it an airport!) is surrounded by 
trees and houses.  The clear area around the cut-out is way too big.
