Some airfields in these rural areas are used by only a few locals. Sometimes they are just a grass field that gets mowed a few times a year. So in places like this it may be very hard to tell if it is active or exists just from satellite imagery. @Amplica, where do you lookup airfields on the FAA site? I have been wondering how to verify airfields if a few other places. I wasn't sure if these small ones had to be registered or not.

On another note, someone just let me know that Google shouldn't be used to generate map data. Thought I'd pass that along @mambus.
