I remember that. I also remember fifteen cent McDonald’ hamburgers.
And there was still a Red Barn hamburgers near me on Woodward in Detroit during the 70s.
I’m from East Tennessee...In the mid ‘60’s we used to cruise Chapman Highway in South Knoxville...Babe Maloy’s, Shoney’s, McDonalds, then go to Smokey Mtn Market for the world’s BEST hotdogs!!!!!!!!
