Back a few years ago when we still lived in MA we got some sort of hurricane like storm. We didn't live near the coast, but our part of town lost power. Our generator kicked in and we were all set.
A little while later my next door neighbor sent me a text. He and his wife were on vacation somewhere and they got a call that the power had gone out. He asked me if there was a way to run an extension cord into their kitchen and plug in the refrigerator.
No problem. He and his wife were great neighbors and I wish we could have packed them up and moved them to TX with us.
So, I connected to 50' extensions cords, plugged one end into an outside outlet, used the combo on their door lock to get in, and plugged in their 'fridge.
I also made sure that their cat had water and fresh kibble as the water bubbler wasn't working.
We don't have any neighbors here in Texas that we know well enough to do that for, but we do have a whole house generator.
