The Heart of Ohio. It's an apt description for a friendly city located smack dab in the middle of the state. Yet for years, the Capital City has taken a back seat to its better-known sister cities -- Cleveland, two hours north and Cincinnati, two hours south. Columbus became the state capital in 1816, and the city's prospects became even rosier in 1831 when the Ohio and Erie Canal expanded its line here. By the 1940s, growth had taken off. Rockwell International built an aircraft plant here, and the city was becoming a hub for large corporations and government offices. It's a trend that continues today, with Nationwide Insurance, Borden, Wendy's and The Limited all headquatered in Columbus.
