“LINFIELD’S ATHLETIC DEPARTMENT AGAIN APPEARS headed for a
first. Next fall, September 20 to be exact, the Wildcats open the football
season at Portland State University in Civic Stadium, therefore becoming a
participant in the first college football game played in Oregon on artificial
turf. Portland is the first city in the world to have the fake turf in an
outdoor baseball-football combination situation.”
