The Big Y Shopping Center was located in the west end of Walla Walla. It had a supermarket, a drug store, and a restaurant. At the end of Rose Street, it was at a Y shape intersection. Driving straight would go into College Place. Veering to the right would go to Wallula Road which would take a driver to the highway to the Tri Cities. The Big Y was eventually owned by my Uncle Dave Barer. The Miller Supply building in the background was later purchased by my father.
