I was thinking about this yesterday. Back in the early 50’s, most people did not own a freezer, and the refrigerators of that time had what was called an “icebox” at the top of the refrigerator. It was only about a foot square, and would hold the trays of ice for putting in summertime lemonade. There was a storage locker for frozen food in Sandpoint, called “Jack’s Lockers”, and that is where my mom kept any food that she wanted to be kept frozen. In the fall, when my dad went deer hunting, the deer meat was kept in the locker, and if mom bought other foods that she wanted to freeze until needed, she put them in that locker. The lockers were probably about 2-3 feet square, and in rows several feet high with a pathway down the center, covered in sawdust (to keep people from slipping on an icy floor). They were wood frames with chicken wire dividing each locker, so the cold air could easily blow through all of them and keep everything very cold. I remember going with my mom to the lockers, and having to bundle up like it was wintertime, and still freezing while we were in there, so the temperature must have been really, really cold. If I complained, she reminded me that I had begged to go along with her, and to stop complaining. Eventually, refrigerators had larger freezer sections, and people bought home freezers for meat storage; but before that happened, renting a storage locker was about the only way to keep frozen food.
