Located in Audubon, Iowa, Albert, the world's largest bull, stands 30 feet tall and weighs in at 45 tons . . . of concrete. Named after local banker Albert Kruse, the monster Hereford statue was built in the 1960s for Operation T-Bone Days, an event held each September to honor the days when local cattle would board trains to the Chicago stockyards. As an interesting side note, Albert's internal steel frame is made from dismantled Iowa windmills.
