WHITELAND, IN - JULY 20: Jud Vaught (R) and his brother Bill Kirklin ride a tractor through their cornfield as they prepare to move their irrigation system to another part of the field on July 20, 2012 near Whiteland, Indiana. Kirklin and Vaught, who are 6th generation Indiana farmers, raise about 1,500 acres of corn and soybeans on a farm founded by their family in 1835. The corn and soybean belt in the middle of the nation is experiencing one of the worst droughts in more than five decades. Indiana was the nation's fourth largest corn producer in 2011.
