You do know that is the reason some of us still call them ice boxes don't you?
WE lived in an old Houston neighborhood called the Houston Heights.
Our daughter bought an old house in that neighborhood and she said she and several neighbors could not figure why they all had a small hill of dirt about 50 feet from the back door.
I figured that when the Heights got city sewage lines, they dumped the dirt where the outhouse had been. After that she referee to that spot as “sh** hill”.
funny....:O)
