An eastern Iowa school board has decided to close one of its school buildings. The East Buchanan of Winthrop board, on a split vote, moved to close the kindergarten through second grade building in Quasqueton after the end of the 2003 school year. The closing is dependent on the Winthrop building passing a state fire inspection. The closing is expected to save 100-thousand dollars. Around 100 students go to school in the building.
