Here's a happy thought: the Heidelberg castle in a bit of sun. Waiting for me on my desktop webcam! Just right there, all nice and sunny on the other side of the ocean even as we speak.
At least I think it's 'as we speak' - I can't make out the little numbers that show when the last webcam photo was updated. And you know what? I'm not looking! As far as I'm concerned, the thought of my favorite castle in the whole world in a bit of sun is a happy thought and I'm all over it.
