Another interesting photo! That is strange that there is no one in sight. We only have one roundabout in our city, that I know of. I find them handy. They are talking of constructing more of them here though. Good plan.
I still remember the photo that you posted way back, of a shoe sole/insert, lying on the ground. It made an impression on me for some reason. Probably because it was so basic yet unique. Made me think.
That is a Good idea for you to start a book with some of your photos from your outtings Hmm, I hadn’t thought of a book. My daughter also loves to take photos when she goes on her walks. She sends her favourite of the week to me to enjoy and comment on. 
This was her favourite taken last week. Not sure what type of bird it is though.
