Dudoight - you and I grew up in the same part of the country.
Everyone had storm shelters and many people (especially those who were better off financially) had bomb shelters. I remember several that were quite sophisticated and very well equipped. We liked to play pretend games in the bomb shelters. Storm shelters were usually more primative.
Duck and Cover - those were the school drills. Would have been absolutely no help if someone had actually dropped a nuclear bomb, but we did them regularly anyway.
On the other hand tornado drills were useful, as we had to take cover many times due to “twisters”. (Does anyone call them twisters now?)
The most elaborate bomb shelter I remember had a thick metal door that I couldn’t open by myself - it had a mechanism like a submarine door to close and had the same type appearance. It had a bedroom area with bunk type beds. It had a living cooking area with tables, chairs, radios, cooking stoves, etc. There were two rooms further back, one a pantry storage area and one a “utility” area to store waste, etc. It was dug into a hill (or the hill was built for it). You went down to the steps to the door.
The owners kept the food and water stocks current and the beds had clean bedding and pretty quilts. There were books and lamps everywhere.
There are a couple of them still left in the county around here. I ought to really go photograph them before they no longer exist. Because of ‘development’ one of them has a road going by right in front of it where a very rudimentary road cuts off the highway.
There are a lot of ‘twisters’ out here!
My granny’s had canned goods, seating and kerosene lamp. This was right in Tulsa. I’m now in ‘rural’ Texas.
