Last week we brought you a story on the Antique Mechanics Society at UC Davis. This week, we're fascinated by ag antiques again. This time we visited the Heidrick Ag History Center in Woodland. Located just off Interstate 5, the museum houses more than 450 old tractors and contraptions. The size of two football fields, the museum feature s the collection of Fred Heidrick. Along with the Hays Antique Truck Museum, the Heidrick Ag History Center was created with the purpose of providing the public with a deeper understanding of the importance of machines to agriculture and the importance of agriculture to all of our lives.
