Nice pic. I'm curious, are those boat slips in the lagoon behind the channel and jetties, and if so why are they ALL empty?
Not "empty." The boats are invisible: you can't tax what you can't see.... ;-)
They are and because that looks to be an early spring or late fall shot based on the trees in the lower right of the shot. Believe me, you cannot find an open slip in Chicago - they are all spoken for for years and years. A star mooring, yes, but not a slip. I used to keep my sailboat just north of the City in a beautiful harbor - Waukegan, and I could get a slip. But not in Chicago proper.
I'm just guessing the the "properties" of the picture say Lincon park. If so, that may be Chicago. If it is Chicago the boat slips are empty because it is either fall or spring and the boats are put up for the winter.
