Look at the Davis Islands on a map and you'll see it has two peninsulas protruding from the very end of it. The one on the right is part of the Peter O. Knight Airport and not easily accessible, but the one on the left is.
And it's a spectacular spot. One can sit at the edge here and behold a view of Long Shoal, Pine Key, and two huge industrial islands that sadly have no names.
In case you're curious, the Davis Islands are twofold, although it feels like one big island when you're driving on it because you're crossing a bridge over a canal early on. There used to be three Davis Islands but the airport sealed up a dividing waterway to build a new runway. Bastards.
