Winterizing Black Tank?

I've been winterizing my trailer for over 10 years now, but I've always wondered about the black tank. Do any of you throw a few gallons of antifreeze down in your black tank to keep it moist during the winter, or do you just leave it dry? I have always put in 2 or 3 gallons to keep any remnants moist, but I wonder if it is really necessary.
