Ft. Johnson and the Dry Tortugas is like Fort Sumter, only
it never got blown to smithereens...

It is "dry" because there's no drinkable water there. The ocean
is the bluest blue I ever saw and clear too... I swam out in the
surf some and it is so cool to be under water there with your
eyes open.
Johnson is a lot like the fort at Savannah we rode out to, only
you have to take a two hour boat ride to get there...
