A couple of old-truck enthusiasts check out one of 20 rigs parked on the lawn on the north side of the Walla Walla Fairgrounds Pavilion, where the 18th annual Blue Mt. Chapter of the American Historical Truck Society show takes place today. Also taking place at the fairgrounds today are the third annual Fall Antique Show and Sale and the Italian Heritage Association Festa. The truck show and festa are free. Antique show admission is $5 or free for those 8 and under.
