2016-09-06 (Day 250) Springfield

In the grounds of the office where I work, there is a strange structure. It is a low cylindrical building, about four feet in diameter and maybe six feet tall.

I've never been able to find out exactly what it is, but I have long thought that a detail from it would make a good photo of the day.

Today was the kind of day where I needed an easy photo of the day from my reserve list of "photos to take when I'm desperate for a photo"

That's the kind of day it has been.
