According to this market research study commissioned by the Mars Snackfood corporation, Nashville is America’s manliest city. Ohioans needn’t fret, however. Cincinnati, Columbus and Toledo were all in the top 10 and Dayton ranked 15. According to the story on the study, "Factors used to determine the manliest city rankings included the number of U.S.-made cars driven in the city, number of sports bars and BBQ restaurants, number of home improvement and hardware stores as well as manly salty snacks consumption." Factors that could doom a city in the rankings included the number of home-furnishing stores, beauty magazine subscriptions and minivan sales.
