Stop signs have been lingering in my thoughts.  I had to get my vehicle emissions test done, and get my license plate renewal sticker.  I guess traffic stuff has just been on my mind.

When I looked up a stop sign image online, I came across this website with the history of stop signs.  Interesting.
