KOQN (Brandywine), a popular non-towered field serving the western Philadelphia suburbs. Notable for its heli FOB on the north ramp and the fixed wing on the east ramp, and for the trees along the runway, large mansion just off the 27 departure, and the over-road approach coming in on 27. It would shine with some ORBX love!
