SOUTH WAYNE - The gazes of 32 students at Black Hawk Elementary were fixed on a screen at the front of the library Friday, which displayed landscape photos of icebergs, penguins and even one shot of Shawn and Patrick Faessler, attached by a long rope, hiking the side of a mountain in the Antarctic Peninsula. The expedition, which lasted roughly 18 days from southern Wisconsin to Antarctica and back, began when Brodhead graduate Shawn asked one question. "I was looking for some volunteer work to do," Shawn said.
