Since Hanover has a lot of alleys, many of the backyards are accessible for photography.  One idea I have had for a while, but have not followed through with, is to feature the alleys in a series of pictures, and maybe even publish a book of the pictures.  In the above image that I made in May of 2017 if you look closely you should note a number of confusing things.  Whether or not I go forward with this idea will depend upon whether I can walk far and often enough to make the pictures.
