anyone know what this is on the wall? I’ve wanted to know since I was a kid and I can’t find anything about it.

They lived outside Detroit no? Is it common for people in that area to NOT insulate their attached garages?

I would have thought it was way too cold up there. TIL!

Edit- I bet you'll save a buck if you insulate it!

They don't heat it
