We visited the US Botanic Garden’s annual “Season’s Greenings” display titled “Roadside Attractions” featuring plant-based recreations of iconic sights from across the United States, with G gauge model trains chugging around, below, through and above the displays.

The “See Rock City” marketing campaign is almost as famous as the Rock City attraction itself. In order to promote the newly created mountainside attraction, painter Clark Byers would go door-to-door offering to paint barns for free, if they let him add the phrase “See Rock City” to the barn roof. This barn is particularly iconic because it’s located along a heavily traveled road. Barns were the canvas of choice for the advertising campaign due to their large size and prime location along the secondary roads that led to Rock City. At one point, there were 900 barns across 19 states advertising Rock City; today, only 62 are still standing. Rock City remains a popular tourist destination.
