"White line Fever",Kenneth! No power steering,and air conditioning was the windows down,and the vents open! Trucks "ran" a lot more 2-lane,(at best) highways,and some routes were more narrow hilly steep and curvy gravel roads,than paved! 45 M.P.H.,was a common speed limit for trucks,and most states didn't exceed 50,on 2-lane highways! This was true up into the early '70's,here in Iowa A lot more physical labor involved,too. No such thing as "no touch" freight! I REALLY ADMIRE you guys! American Backbone!
