Imagine how the freeways used to sound like in 1972

Yesterday I went for a trip to my neices about 1/2 hr drive away in my 73 Dart Sport(372ci,4 speed with 3.23).I had my 5 yr old daughter in the back and my 80 yr old dad in the front LOL.My daughter asked...Daddy why is everybody looking at us with thumbs up?LOL.Was good to see my dad give the thumbs up back.LMAO.I kept it at 60mph on the highway,dads on oxygen.
