In the grand scheme of things, winter in Columbus, Georgia and generally the south, is, by most measures, a relatively mild affair. We don’t see the deep freezes of northern states, nor are we blanketed in snow for weeks on end. But in the unpredictable rhythm of weather patterns, winter in Columbus presents its own set of challenges. The occasional cold snap or early-morning frost has a curious way of revealing vulnerabilities in even the most well-engineered machines.
