Another picture from the recent day when I was out cruising for infrared images. This is the intersection of Fourth and Market Streets in downtown St. Louis, taken from behind the wheel of my car at a stoplight. The building in the foreground is what we call the Old Courthouse, parts of which date back to 1828. Hard to believe considering what's behind it, but it was the tallest building in Missouri until 1894. It's now run by the National Park Service.
