Home Field Advantage.: The Trona (Calif.) Tornadoes played their final game as an 11-man high school football team on Friday, defeating the Boron Bobcats on a field known as The Pit. Why? Because it has no grass on it. "Apart from the football field at Juneau High in Alaska, which is made of glacial silt, Trona may have the only all-dirt field left in the United States." The town is a last-chance stop before entering Death Valley. (NYT link: u: SportsFi, p: SportsFi)
