You may have already looked in this program's TRIVIA section, but in case you overlooked it, one entry reads:

"Although the names of the towns in this show are assumed to be made up, there is an area of southern Tulare County, California - a rural community about 175 miles north of Los Angeles - that has several towns whose names are suspiciously similar to those in this series: Porterville ("Hooterville"), Dutch Corners ("Crabwell Corners") and, in fact, there actually is a town in the vicinity called Pixley."

Not a great help, but you might want to follow up by searching the Tulare County home page and see if there is a reference to Green Acres. If the fly over was shot there, they would surely say so. There is not a whole lot to brag about in Tulare (to any residents, if I am wrong, correct me. Bona-fide residents only).
