Your (nicely photographed) picture and your commentary made me chuckle! I certainly know what you're talking about! Often I feel as though this is some sort of obsession, and then I realize...it is! I can't say what it is that keeps me coming back for more as often as possible, but it's a lot about the challenge, the friendly people, and more pictures to enjoy than I can possibly hope to see in the course of the day! *yikes*!
