CLEVELAND, Ohio (AP) -- Walking the towpath of the 19th century Ohio & Erie Canal, deep in the Cuyahoga River valley amid chirping birds, croaking frogs and the smell of honeysuckle, you could easily forget you're in Cleveland. Just ignore the clanking freight trains overhead, the power transmission lines and the skyline in the distance. After all, this canal, nestled between steel and chemical plants, is part of Cleveland's history as an industrial powerhouse. But like many places connected to this Rust Belt city's past, it has been cleaned up and reborn.
