-and there's always great food, awesome artwork by CCAD, and other stuff. there's almost never a dull moment in columbus.

Tons of restaurants and ambience, not to mention the Columbus Crew soccer franchise.

A correction for the first answer- it's Easton Mall, not Eastland. And yes, it is the best mall I have ever been too. It has mostly outdoor shops, but a lot of indoor ones as well. It has a huge gaming arcarde and sports bar, an AMC 30, and an ice skating rink across the street. Wonderful place to visit!
During Christmas time, they have a huge tree and carriage buggie rides.

The Columbus Zoo is also worth visiting. I thought it was a very nice zoo and would love to go again.

The airport is smaller and easy to navigate through. The country side is beautiful, and it isn't far from Amish country.

It has many historical sites, though I am not sure of their locations.

I hope I helped!

do to disney land and magic mountin...
