Thanks for the reply...

As it turns out I am not using a cover, and no pillow either...

With all the cold we had so quickly this month, the pool is already an ice cube... I don't know if it goes down very far or not, I haven't been out to check on it since I have been recovering from doing 12-16 hour days getting the patio finished... My hands are still far from "good" and still heavily calloused.

I did get all the hard lines off, lines blown out (added about a gallon of anti-freeze per line "just to be sure"), everything plugged and added about 3 gallons of anti-freeze into the main drain on the pool. Everything is capped off and "done". Water was drained to about 2-3 inches below the returns. Basically got it all done the day the cold front moved in, as the temp dropped from 39-40 in the morning to about 30 degree as I was finishing up at 2-3pm. I drained the cartridge filter, even removing the plug underneath and fully draining it, as well as bringing in the pressure gauge. The filter is still outside, as it will take me another week or so to make room in the garage for it. But, eventually the heater and the cartridge filter will be moved into the garage as well.
