The natural range for the longleaf pine starts in Texas and Florida and goes to the Atlantic Ocean and the Gulf of Mexico, but it ends in the north and west in Brunswick County, Virginia. I have been studying the map and it looks like the natural range of longleaf ends precisely in the middle of my property in Freeman, where we planted longleaf pine.
Therefore, I believe, or at least will assert, that my land forms the northwest terminus of the natural longleaf range. Next time I go to the farm, I will paint a bright line to mark the border. Perhaps it will become a minor tourist attraction, one of those things worth seeing but many not going to see.
