Not sure if any of you would know about this, but I live in NW Indiana, and remember watching a show as a child that talked about things like cows and milk. It was on what I assume was a public access channel, a channel called Lakeshore something-something. The show had this farmer looking guy around some children that would explain and show stuff like how to properly milk a cow, how to pasteurize it, and the various fat levels of different kinds of milk. I doubt this will be a big find, but this is sort of interesting to me.
