Best way to winterize yet still use unit in winter?

In Atlanta? I wouldn't think there is much of a winter.
We lived in Maryland. We waited until the first long hard freeze to winterize - as early as November or as late as January. We kept the tanks and water lines dry and put antifreeze in the traps. Our first season, we winterized/dewinterized four times(antifreeze in the entire system). It got old quick. But on those trips, we took drinking water in jugs.
