My grandma, who is 97 years young and lives on her own in a remote area of northern Wisconsin about 15 miles from the U.P., freezes milk in pint jars so she won't have to throw out spoiled milk all the time since she doesn't go through a gallon very fast by herself. She's done this for quite a while, initially because of the large amounts of snow up there and not knowing if she'd be able to drive to the store. Then, her driver's license wasn't renewed a couple years ago (and she's still pretty pissed about it!), so she has to wait until someone takes her to the grocery store. When she does a big shop, she buys three or four gallons of milk, then comes home and immediately breaks it down into pint-sized portions to freeze. As she's using one pint, she has another pint in the refrigerator thawing out. My sons, now 19 and 21, enjoy helping Great Grandma with grocery shopping and freezing the milk when we visit a few times a year. Long answer, I know, but the question made me think of my grandma and smile. . . .
