My field trip was EXTREMELY helpful. If it’s possible to do research via the actual location, instead of ONLY using the internet, then do it! I acquired a great deal of knowledge from a very hospitable dairy farmer in North East Maryland. He answered all my questions, and I even milked a cow!
I’m not used to this farming life, though! That stench sure is strong, but the cows are lovely! Running a dairy farm is a lot of hard work since those cows are on a schedule!
