Pi r squared

Back on the hidden Cirencester challenge - to find 100 photos taken within 1 mile of the church in the centre of town.

So I guess that is 3.14 square miles that I have to search to find these random pictures.

I got this one today - just a very small window with the disc like object on it. I have no idea how I spotted it.

That’s 76 found. Just 24 to go.
