Metrowester, I agree that Nashville shouldn't be lumped into cities with identity problems.
And on Jax vs. Charlotte, I've lived in both. Jax could not compete with Charlotte (except in football) 10 years ago and it certainly can't now.
For having no name recognition and no hook except banking, Charlotte seems to be creating its own hook -- not too big, not too congested, not too polluted, not too crime-ridden, not too hot, not too cold, not too poor, not too rich (oops, we're getting there). Just right -- for now.
Of course, we have to figure out light rail and schools. Nobody's perfect.
