Lurker

I was in my boss' office this morning for a meeting when he noticed something on the window behind me. We looked out and there was this rather large spider with a big web on the window. I decided that if it was still there when I left for the day that I'd grab a few shots and, sure enough, it was still there at the end of the day. I'm not sure what kind of spider this is, but it was pretty gnarly looking.
