Mark Zuckerberg paid a visit to Wisconsin. It's part of his effort to visit all 50 states and meet with Facebook users.

Yesterday he was in Blanchardville, Wisconsin, west of Janesville. He met with the Gant family which owns a dairy and cattle farm.

Zuckerberg said in a Facebook post that he fed a calf, drank unpasteurized milk, and drove a 70-year-old tractor.

The Facebook CEO also paid a visit to "State Street Brats" in Madison. He ate two brats and some cheese curds and said in his Facebook post, "I do not regret it."
