I can remember when I was in high school all convenience stores and what we here in Texas call ice houses,on display you could buy
any caliber shotgun shell,rifle and 22 ammo they had in stock.We all drove pickup trucks with a shotgun,22 or deer rifle on the gun rack rear window of the truck.
We never locked our trucks and we all carried pocket knives to school.
I was in the 9th-12th grade in 1963-1966.
