Dublin...I say there's two dublin's.  There's Dublin-dublin, which I like to consider is outside 270 and north of 161.  That's the nice expensive dublin.  If I had the money, I'd live there!  Then there's other dublin...dublin-columbus.  it's inside of 270.  There are nice areas here but typically you pay columbus taxes but get dublin schools!!!  Either way, I don't think you can go wrong living in either section of Dublin and I highly recommend it.
