Locks Textures

In the recent past I ventured to the Ballard locks for an afternoon. It was warm and sunny and there were quite a few people milling about. My girlfriend and I went to shoot there, and after a short while of walking about, I was captivated by the walls of one of the locks, and the colors and textures it had. The images are a small group of those textures and some of the variations we saw that day!
I figure it's probably better if I mention the metadata (camera settings) that I used to get some of these shots, so here it is!:
ISO125 F/8 1/100 @ 40mm (18-50mm lens), polarizing filter
