Last weekend we went to the Hilmar Cheese factory here in central California. It was mostly a gift shop/deli/coffee shop on the first floor and the second floor had window views of the inner factory as well as educational things about cheese. There was a giant fake cow to demonstrate the milking process and a mini replica of the dairy behind the factory. We got to see the factory workers making cheese and test out the famous "squeaky" cheese. Another good field trip I'd say!
