I'm probably the last generation to ever experience Blue Laws here in NC. I remember as a little kid, even early teens, everything was closed on Sunday. It was absolutely wonderful on a Sunday afternoon. Hardly any traffic out except for some folks visiting relatives and so much quieter.
After fleeing the thug-controlled state of Ohio (1969), East Tenn. and South Carolina were such righteous places to live. I know what you mean.
The Bible states God's blessing will not be on a people or nation which deliberately turns the Sabbath (Lord's day) into just another day of merchandising and pleasure. We are on this earth for His pleasure, not ours.
