Case #1, Marvin High School, is in the small, unincorporated town of Marvin surrounded by massive agricultural flatlands in northern California. It is in the smallest of the four school districts in the county, approximately 45 miles from the closest city of over 50,000 and the closest State University, and about 75 miles from a city over 200,000. Approaching town, drivers pass open fields, a hunting preserve, trucking operations, grain elevators and a country market. There is one flashing red light near the railroad tracks approaching the center of town and no other signal lights
