I lived in a cabin that had a refrigerator, but didn't always have electricity. Not a problem in winter, but in warmer months, people who didn't have smokehouses would coat all their meat with a thick layer of salt, put it in sealed containers or wrap it up in layers of butcher paper, and bury it at least a couple feet deep. But bears, foxes, and wolves will dig it up if they smell it.
What you have to do is hunt for food you can eat up within a few days. So you have to hunt or fish a lot more often in warmer months.
