[Talk-us] [Tagging] Aeroway=Aerodrome Modifier Tags?

As a side note to the airport tagging discussion, it strikes me that, more
than any other area of the world I've looked at, the USA at zoom 15 in OSM
is littered with airports/airfields.  Most of these were added by the GNIS
import.  Either the US has a much greater density of airfields/airports than
other parts of the world, many airfields/airports have yet to be mapped in
other areas of the world, or the GNIS import brought in a bunch of airfields
that are no longer in operation.

Has anyone noticed a bunch old airfields in their area created by the GNIS
import that really shouldn't be on the map.  All I know is that when I look
at the aerial imagery where some of these airfields/airports are supposed to
be, all I see is a field.  Could be that it's just a grass runway….  In my
town there's one airport that's supposedly in the middle of the golf course.
