Side of the road

One is an image, while one requires a bit more of an explanation (or maybe doesn't, but you're getting it anyway).

First, stapled to a telephone pole, a yellow sheet of paper with "He'll be back. Merry Christmas." written in black permanent marker.

Second: The Great Lakes Science Center has a renewable energy exhibit -- a rather prominent windmill, and a number of solar panels outside. I usually don't drive that way, but did tonight. 

Each of the solar panels was bordered by purple Christmas lights. I assume they're solar powered, as well. Pretty and cool.
