Get the book! The following took place in 1976 on the soon to be pope's visit to Wisconsin.
Matt JK: JPII scales silo wearing cassock in portage county, great story! (my emphasis)
Portage County is generally known as a flat area with little change in elevation. It is often referred to as a plains area and is a mixture of agricultural fields and thick forests. Wojtyła had a knack for finding the highest place in a given area in order to survey it. As a result, when he noticed that the highest point on the farm was the silo, he naturally asked if he could scale it. The Zdroiks, especially the boys of the farm, were quite surprised by the request and at the same time impressed. They had never seen a Catholic priest, much less a cardinal dressed in his black cassock with a golden pectoral cross hanging around his neck, scale a silo. Yet, his clerical garb did not deter him, and Cardinal Wojtyła climbed the vertical ladder with relative ease, reached the top of the tower, and gazed over the vast plains below. He wanted to see the “green of America,” and that is exactly what he saw.33
Lots of footage, media interviews
