I just downloaded the new Mifflin scenery addition to Condor Flight
Sim. I have never flown out of Mifflin in real life (yet-...must
rework the Lak-12 trailer...). I took a ASW-22 up for a flight and
recognised many terrain features from my favorite soaring movie "A
Fine Week of Soaring". The best one being the notch in the ridge on
approach to the airport.

If you have not tried Condor it is simply the best soaring simulator
out there.
