I'd-a thunk Duluth woulda had one of the very first Costco locations.
Costco only builds warehouses where certain economic demographic criteria are met. If they're not met today, they might be met in the future when the location is revisited for the criteria.
Therefore, Duluth has never met the criteria until now - which is why Costco's only Mississippi and Arkansas locations only just recently opened.

Seattle, WA was the very first Costco back in 1983, followed by Portland, OR, then Spokane, then Salt Lake City. Many of the older buildings have been relocated to newer, larger, buildings and the building is renumbered. The renumbering happpend because when "01" got a new building, the number was kept the same as that was the thinking at the time to keep the number the same - but it caused logical nightmares for the opening: Which "01" are you referring to? The old one or the new one being built? Which building is supposed to get the delivery? It caused
A LOT of unhappiness and grief at the distribution center.
After that nightmare, renaming the building the old number never happened ever again. Also management, at the time, was still the old guard founders wanting to keep "01" as "01" fo sentimental reasons.
