I wanted to add this more-realistic highway roadsign, thanks to kilroy_2525's creation. Courtesy of Wikipedia Commons, 2004 Edition of the Manual on Uniform Traffic Control Devices, Sign #M1-4. All U.S. highway markers and traffic-control signs from the Manual are considered in the public domain, except for the U.S. Interstate Highway Shield, which is governed under "fair use."
