In response to post 2211 of hemmjo and roadway tests. There are rather distinct highway signs a little west of Ottawa, IL mentioning same tests, at least in one locale. Our highway system was influenced upon General Eisenhower first hand, seeing concept in post war Germany. His state of Kansas commemorates him too, certain highways, interchanges and so on.
Our current administration is so uninformed; no clue what infrastructure really means.
I'm no kind of truck driver, yet clock untold miles over eastern Midwest retrieving equipment far away as Michigan, Pennsylvania, Tennessee with little apprehension and lots of appreciation. One habit of every trip includes a little Johnny Cash; [of course; it's me after all] "I've Been Everywhere".
Who cares, 'Everywhere' is subjective, taking it to be 'everywhere worth going'. This month alone, ~3200 miles, some looking for a spot hidden west of Dallas/ Fort Worth. Not the one south of, lol.......
