The fig belt is only Birmingham and south?
Absurd. But with an explanation.
Birmingham is about as far north as Atlanta. There's a commercial fig grove 20 miles from me here in VA which is about as far north as Washington, D.C.
When I visit my mother and her hubby in South Carolina there's fig trees everywhere.
So there's plenty of figs north of Birmingham.
I, do think though, that he may be talking about strictly commercial groves with no tourist component, etc. in which case I can understand that he means that the groves set up to produce figs for retail and wholesale bulk sales are set up pretty far south to take advantage of the heat, long summers and almost frost free temperatures.
Nice video . thx.
