Take the back roads here in Centre county and you'll come across a quarry or a lime stone processor like this.
From the amount of lime dust on the factory, you would assume that we haven't had rain for quite a while. Not true. It's been exceptionally wet this spring. It takes more than a few April showers to scrub away decades of crud like this.
I've photographed this building once before when I was playing with long exposures and night photography. In the harsh light of day the romance dies. Still, I love the contrast of white on rust.
