Carmi at Written, Inc., posts a photographic challenge each week called Thematic Photographic - this week's theme is "signs that make us wonder."
Just after I posted my first sign for this theme, I was driving in to work and traffic was backed up on our winding, two-lane mountain road. I was stopped behind a long line of cars, and I looked to my left and there by the side of the road was this sign someone had nailed to a tree.
Truly, a sign that makes us wonder!
How nice that a traffic jam allowed me time to notice it and to take a photo!
