The “Southernmost” Point of the continental United States isn’t, as a quick look at a Key West map will tell you. There is a point further south on the island, but it is behind the gates of the US Navy’s Truman Annex, and thus inaccessible to the public. So it’s more correct to say that it is the southernmost point of the continental United States that isn’t on a military base. There! How’s that for accuracy?
