The state capital of Ohio, and the 15th largest single city in the US, with about 730,000 people in a metro area of about 1.8 million. It has a low profile, due to its general lack of pro sports teams (except the NHL's Columbus Blue Jackets) and not many people outside Ohio and the Midwest know much about it, but is more known for OSU Football. The city loves to beat up on the UM Wolverines. Columbus is a major college town (OSU is the 2nd largest university by student body in the US) and is actually a nice city, with good jobs by Midwest standards and plenty of places for young people to hang out. Although Columbus is not necessarily a "big" city or a major US City, it is in the same tier of its peer cities like St. Louis, Kansas City, Louisville, Cincinnati and Indianapolis, with which it is probably most similar.
Columbus, Ohio is a major college town and a good place to live in general.
