Yes I have the same problem in western Canada. The more important and popular airports are detailed and accurate. In fact when I land in Calgary, Ground Control tells me to taxi and park where the Executive Air Centre is. At Springbank, GC has me park in front of the cafe. Somebody knows this place!
But a lot of other fields, out in the rural boonies, show runway only, no hangars, no correct roads, just prairies and trees. One real grass strip, beside a real farmhouse, in XP is modeled in the next field over, with fabulous night-lighting that I can see from the next county over. I say "thanks".
It might be fun to drive out to the real fields around here and update the XP scenery.
