Finished moving the cellar into its new location:
It's a pretty narrow space, only 6', but I think it'll work well. Plenty of space to expand, which is good, though I kind of hope I don't need it. The thermometer was reading ~58 before I had the lights on and was moving around in there for hours, so I'm optimistic about temperatures. I'm going to put some insulation on the walls and ceiling at some point, I think it should keep pretty cool after that. I'll also need to build a wall/door at some point, this is right behind the furnace and water heater.
Also, this took way longer to do than it should've because of:
Those are rat tracks, in case you can't tell. Among the many move things about moving into my own home is that I can actually control this space, so there won't be any ******* rats in here. Cleaning every single bottle took forever...
