When I first started hunting Ft. Stewart in Ga. right when it opened to public..around 1960 I think, feral cows were legal in there.
I would see plenty of cow tracks down the dirt roads, etc., but never saw a cow and never knew anyone that did.
I walked up on a big Brahma Bull deep in Greenswamp WMA in SW Fl. one time. Every now and then a few cows would get through the fence on bordering property back then..Hampton Ranch..but as far as I knew they weren't legal to shoot in there.
Quiet a few of the Fl. WMA's have Brahma's in them..but they are not legal to shoot. Tosohatchee, WMA has a lot and I hated having to walk through them before and after daylight coming and going.
