>Sure, make sure you are getting paid what the market will bear. The cost of living I am sure is less in Tennessee than other 'major' metropolitan areas. There are many factors making a salary...

You got that right. I'd be relatively "wealthier" than I am now up in Maine, where I previously lived, if I made 1/2 what I currently make in the DC area. So much of a salary is relative to the COL in a given area, on top of supply & demand.
