I don't know about that.

Yes, definitely.

I don't know if it is a bunch, but they certainly are there.  I did a
little research last year, and it looks like the GNIS list came from an FAA
list.  It appeared to include such things as clearance requested and
granted for airstrips but never built, and former airstrips that have since
been replaced by new construction.

Those do exist.  Whether they merit inclusion on the map is subjective.  I
think the large/medium/small size suggestion is a really good idea.

There are some golf resorts with their own airstrips.  But if you know the
area, and know there is a golf course there and no airstrip, by all means
feel free to fix the map and delete the obsolete airport item.

Thanks for keeping an eye out for this stuff.
