I saw a big hill at one end of town and decided to scramble up it on my lunch hour. At the top was something odd. A building with concrete walls, no windows, a few vents, and it was surrounded by razor wire. Oh yeah, and it only stood about 2 feet out of the ground (I'm assuming that it delved deeper into the hill).
If I were to take a guess I would say that it is related to water distribution, but that is a shot in the dark. Anywho, the sun was shining right where I wanted to take the shot, so I decided to include it in a 3 exposure HDR:
