The original retail rival of SUNSET CENTER was a small open-air, cluster-type complex. WOLFLIN VILLAGE opened in the summer of 1953 and is in business to this very day.

Next came WESTERN PLAZA, a fully-enclosed mall, which was dedicated in early 1968. After a prolonged commercial demise, it was shuttered in April 2006, demolished in June 2007, and replaced by WESTERN CROSSING. This power plaza held its grand opening in November 2008.
