If you have a power outage that is projected to last more than a day, your freezer contents will start to go bad. So if there is a lot of snow on the ground and freezing temps outside, bury your most expensive or hard-to-replace freezer contents in sealed containers in a snow bank, and set up some kind of barriers around the pile to keep critters off (we have deer, bird and fox marauders). I saved half a dozen crab cakes and some steaks that way last time.
Good tip!
I never throw out a cooler.
When it is broken, like the lid came off one, I still saved it and use it for utility stuff like that.
Primarily I use it for defrosting my freezer. When we get temperatures forecast to be in the single digits, I get out all my coolers, fill them with the contents of the freezer, and park them outside somewhere safe. I actually put some in my car and locked it up for the critter factor.
Then I can take my time to defrost and clean the freezer well.
Nice thing is, I can organize it when I load it back up.
