One of my favorite little corners is an old school website designed site that’s still actively maintained at http://www.airfieldsfreeman.com
There are TONs of pictures of little known or abandoned airfields all over the country. It’s really fun to go back through.
I live in Asheville NC and my favorite of the bunch was an airport across from the famous Grove Park Inn Hotel.
That airstrip is now a man made lake.
