Athora- I agree completely with what Catzia said. Columbus is awesome and I'm very happy we made the move here. I moved from NYC, but I was ready to make the change to a small city. I'll always love New York, but I got tired of the never ending stress and the housing costs were getting out of control. Columbus was a very welcome change for me and I find life here more refreshing. People are nicer, streets are cleaner, it's got a fun artsy local vibe, and people who live here really seem to care about what goes on here. The thing I miss most about New York is the ocean, so I can only imagine how tough that may be to give up if you're already living in Southern California.
Definitely try and visit and see how you like it!
