Kenworth Truck Co. recently invited journalists to test drive five of its vocational trucks in Snoqualmie, WA, at the site of one of the most prestigious professional rally schools in the U.S.: a place known as "DirtFish" that is situated roughly 26 miles from Kenworth’s headquarters in Kirkland, WA. A century ago, it was the site of the Snoqualmie Lumber Co., later renamed Weyerhaeuser. (Photos: Neil Abt/Fleet Owner)
