Cable failure is mostly a function of age and cycles, and Virginia City's housing median of 1938 puts a lot of doors here well past the point where original hardware is still doing its job. Cables stretch, rust, and fray with use regardless of climate, but the cold-and-severe winter band this whole region sits in adds its own wear: metal contracts in cold, grease stiffens, and a cable that's already thinning is more likely to catch and fray on a cold morning than a mild one.
With only 396 households in Virginia City itself, this isn't high-volume territory for any garage door company, which also means fewer doors here have had a recent full service to catch a fraying cable before it lets go. A median household income of $108,214 locally, a bit above the wider service area's $102,625, doesn't change the physics, but it does mean replacement with upgraded hardware is usually on the table if a door's cable failure turns out to be one symptom of a bigger age problem.
