The strangest things...

Turn up in the most ordinary places. This is behind a small toilet block on the green just opposite where I live. The toilet block is a new addition to a very old village green and is locked, oddly (and annoyingly when potty training a toddler).
When I was out with Elizabeth this afternoon I spotted these and still can't figure out quite why they are there...the green is used just once a year and that is for the May festival. I guess I'll never truly know...
