The 109 giant ears of corn on a lawn in an office park near the town of Dublin is a project conceived by the artist Malcolm Cochran, in 1994, for the Dublin Arts Council. It makes a statement about the transition of much of Ohio's landscape from farms to suburbs. The site, once owned by an agricultural researcher who hybridized corn, is now across the street from a new Nationwide Insurance company office, where 1,500 employees were recently relocated from downtown Columbus, a city that has one of the highest downtown vacancy rates in the nation.
