While I was at Wisconsin, someone invited me to visit their farm. It was quite an exciting trip, as I had never really been to a farm before! Finally I could get close to a lovely red barn, to bales of hay and walk by green rolling meadows.
The highlight of the trip were undoubtedly the holstein cows. I got to milk one of them.
This probably was a pH meter, though I'm not very sure as its been quite few years.
The intrepid farmer at work.
