The region hosts two-week-long visits by the Ringling Bros. and Barnum & Bailey Circus each year with multiple performances at Norfolk Scope and the Hampton Coliseum, and even attracts a group of Circus Train Enthusiasts, railfans who watch, photograph and report on the blue or red unit trains as they make their move between the two sites, requiring a long inland trip through Petersburg and Richmond in order to avoid crossing the 10 miles geographical distance across the harbor (a trip impassable directly by modern trains; the two bridge-tunnel facilities operated by VDOT accommodate only highway traffic).
