SPENCER, Iowa — A former Minnesota man, now a high school coach in Spencer, turned hero for rescuing two boys stranded on the flooded Little Sioux River. Evan Scheck, who grew up in Houston, heard the boys yelling for help after they were swept away by the current. The boys had been trying to ford their bikes across a flooded trail. Scheck got the boys safely out of the river. The Little Sioux flows out of southwest Minnesota into Iowa and the Missouri River.
