Freeze damage to yer Mopar?

Orielly gets 20.99 for a gallon of Zerox. Tax and all was 23.53. And this 50/50 mix! I felt like a fool paying over 10 dollars for half gallon of water.
I recall when I was very young, my grandpa would drain the radiator, leave the **** open, crank 59 Galaxie and drive the front end into a huge shrub. Keep the cold wind off of it. It worked. The garden hose was always left open both ends and laid downhill toward the shrub/car so he could refill the next morning.
