waiting in line

So pier 33 is the where the ferry to Alcatraz leaves from, but I had some time to kill waiting for my boat. When what should happen but a military vessel should come sailing by. At first I thought that it was cool, but then I saw the flag on the aft, and I thought it was even cooler. Unfortunately the fog started to roll in at this point, so my images are even worse then normal, but they are what they are.
