Along Illinois Rt. 159, about 1 hr south of St. Louis.
A good example of "The best camera is the one you have with you". We had to make a quick run to Redbud Illinois, which is about 1hr drive from us (each way). No time to dawdle, so I didn't take a camera. But I saw this sign on the way down, and noted the location. We pulled off the road on the way home, and took a few photos with my iPhone before continuing home.
