Great observation, Old Timer! It's still a nice shot - we can't control the conditions we're going to get, but there's always a great image to be made. Part of the challenge.

Your story reminded me of William Neill's Dawson Lake photograph. I can't link directly to it, but you can see a link to the poster on his home page. He shoots 4x5 and was waiting for a sunrise that never came. This became his biggest selling image!
