Best sightseeing in San Diego part 7

Did you know that all bananas for the 11-most-western states are distributed from San Diego? A 'banana boat' arrives every Monday in San Diego from its travels from South/Central America. Trucks are loaded and we get our daily doses of potassium.

Notice in the second picture the ring hanging on the line.  Can you guess why it's there? Can you think of who else likes bananas that hangs around shipyards...?  (Reminds me of my dad putting a metal skirt around our biggest tree in our backyard to keep the squirrels out of the bird-feeders;)
