Homer's own numbers explain a chunk of this. It's a smaller town - 1,566 households against the wider service area's 18,597 - so the commercial buildings here tend to be single-owner, single-bay operations rather than the multi-dock warehouses you'd find on a bigger stretch of the route. That means less duplicate hardware if something fails and a longer wait for the right part to show up on a truck. Add the climate: this whole service area sits in a cold-severe band, and a door that cycles all day at a shop takes that cold harder than a house door that opens twice. Higher income here - $106,618 median versus $78,155 across the wider area - tends to mean better-spec doors going in to start with, insulated panels, heavier openers, but that only buys you so much once ice gets into a track that's cycling forty times a day instead of two.
