I found a little glitch in the Aerofly FS 4 terrain. Close to KSFO airport, there is a hill with the inscription "SOUTH SAN FRANCISCO - THE INDUSTRIAL CITY"
In fact, if you drive from KSFO to San Francisco, you can see that hill and its inscription.
The inscription is clearly visible in Aerofly FS2:
But not in FS 4:
You see: There are buildings on the hill that imitate the shape of the inscription.
And this is the view from Googlemaps:
Keep up the good work! All the best, Gianni
