Welcome to Fort Jefferson. You got here by boat or float plane as it is seventy miles off the coast of Key West, Florida. Built over a thirty year period ending in 1874 the fort was never attacked, never completed and never fully armed. Yet it did protect vital shipping interests in the Gulf and was the final fueling stop for the naval forces during the attack on Cuba. It is now a National Park, The Dry Tortugas. Rusty Harman and I visited here in a float place from Key West, an adventure all by itself. Interestingly I was here the same year I was at the Arctic Circle in Alaska almost 6000 miles apart and still in the US.
