Ladybird Johnson as they called her, President Johnson’s wife of the U.S.A. was the first to remove all those commercialized signs along road ways and side streets as they took away the beauty of landscape and were also a distraction to drivers of any motor vehicle..you may see some scattered around u.s.a..but so much distance and feet still required. Even speed signs are limited in size. So your writer is from your neck of the woods
