I worked at the former Eastbay store in Milwaukee on Brady Street during college. At the time the owners explained that the Brady Street store was the original Eastbay location and that several others opened during the 70s and 80s around Wisconsin. Eventually the Wassau store took on catalog sales and outgrew and eventually bought out the others to become the large company it is today.
The Wikipedia page for Eastbay does not include any mention of retail stores outside of Wassau. Does anyone know the real history of the early Eastbay stores?
