If worse comes to worse go to the dollar store and buy some gallon rubber maid pitchers and fill your own. They may not freeze as well but at least it will be drinking water.
Flyer: you might try Gerland's @ the Dairy Ashford exit for some of those gallons.
I already intended to fill the bathtub for washing water, maybe toilet flushing, etc. I have a PUR filter that I will use for filling any extraneous empty soda bottles between now and zero hour.
