I like the 3rd one with the bottom cropped off a bit (to 4x5 ratio).
Don't feel weird about being drawn to strange subjects for no reason. I'm drawn to electric meters for some reason, especially old ones. I don't know why, and I don't care. Sometimes in photography we don't need to understand. I tend to think though, that it may be something, an emotion or feeling inside of us, that is conveyed through a need to photograph something. I'm sure if we digged deep enough we could figure it out, but life is a journey.
