You just took me on a walk down memory lane, lol. I remember seeing the shields blocking the beer from view in the refrigerated shelves at convenience stores. They couldn't remove them and sell beer until after 12 noon.
Joining you on Memory Lane where in the Kansas of my youth it was NO BEER sales on Sunday. We lived 3 miles north of Oklahoma and there was a roadhouse just across the border for a beer run. That place made its profit on Sunday beer sales to KS residents and made a pretty good burger, too. I've been in Kentucky the past couple of days and noted that the no Sunday sales is the law here yet today.
As to hunting on Sundays, my current state of Oklahoma used to limit quail hunting to certain days due to population management rather than concerns about where you spent your Sunday.
In SC on the early 80s, you couldn’t buy things like batteries, etc, on Sunday.
I think blue laws were perhaps well intentioned, but very misguided and counter productive.
