I seem to shoot quite a few antiques, old buildings - aged things. Old things/places seem to house some kind of residue of where they've been, or things that have happened in/around them. It's kind of like a person wearing the past on their face.
Side note: Went to see the DaVinci exhibit at the Des Moines Art Center, in a word, amazing!
