Millington's housing centers on 1972, the oldest median build year of anywhere in the service area - most of the surrounding towns run newer, into the 1980s and 90s. That matters for cables specifically: doors from this era were built with galvanized aircraft cable on steel drums that weren't always zinc-coated the way later hardware was. Fifty-plus years in, a lot of that original cable is still in service, and it fails by fraying strand by strand rather than snapping clean, which is why you'll sometimes notice the door starting to hang crooked before the cable actually lets go.
The cold moderate climate here adds a second factor. Cable and spring steel both stiffen in cold weather, and a cable that's already down to a few intact strands is more likely to finish failing on a cold morning when the door gets its first real pull of the day. We see more of these calls in winter for that reason, not because the cold damages the cable directly but because it's the stress that finds the weak point.
