Curt;
First, great picture!
Mobile, Al has a tradition of inviting ships from the Navy, to come in to port during Mardi Gras. One year, the USS Alabama,(the sister to the San Francisco). Mobile's ship channel, at that time , was only 40' deep. The sub's have a deep draft when fully loaded. Prior to it's arrival, it stopped somewhere else, and off-loaded some "stuff". They never said what they unloaded, but there was speculation, that the Trident missiles was it. Instead of the sub coming in under its own power, three tugs were used to bring it in, to keep the sub in the middle of the channel, so it wouldn't run aground, possibly damaging the main sonar dome.
Even with the tugs moving it, the crew stood on the deck in their dress whites, Impressive Indeed! When the sub left at the end of the Mardi Gras, they had to tow the sub backwards down the channel until they were back into the Gulf, because even the turning basin for all the other ships, wasn't big enough, or deep enough to turn the sub. Due to the rather shallowness of the coast where the Bay meets the Gulf, the tugs had to tow the sub out almost 10 miles to get into deep enough water where the sub could move under its own power.
This was not long after her shakedown cruises, and her acceptance into the fleet, so she was basically brand new. During a ship's stay there, the ship is open to guided public tours, etc. Needless to say, there were no tours for the Alabama. I was fishing in my bass boat, in the Bay, there around the Battleship USS Alabama, and I was able to get a real good shot of the Battleship, and the sub as the she passed by about 1/4 of a mile away. This was shot on 35mm film as there wasn't any digital cameras on the market at the time.
I'll check my stash of photos, and see if I can find it or the negatives, and post the picture. (There's over 20 boxes of pictures that I have to go through, so it may take a day or two, assuming I can find the shot).
