I've always been a fan of "textures". I remember taking a black and white photograph of an old gasoline pump in the town where I grew up (Concord, MA). It was on the side of the road near an old farm and it probably was put in for the local farmers at one time. I liked the rust and peeling paint and took a close up photograph of the side with just the peeling paint. My art teacher wasn't that impressed but I wasn't deterred. I still enjoy photographing "textures".
