California Angels at Texas Rangers. My dad took our family and we sat behind the visitor dugout at old Arlington Stadium (which was unusual as we would sit on the home side after this) so that my dad could introduce us to one of the Angels that he taught and coached in the Dallas High school system, Dave Chalk. Got his autograph on the program still today.
