I lsaw a bumper sticker last week that said, "Welcome to Nashville! Y'all go home now."
The growth in middle TN right now is crazy! State and local gov't are scrambling to have enough infrastructure support: roads, schools etc. Plenty of former CA people, but also lots of immigrants from many countries. Lots of people who come here for college never leave.
I grew up in the midwest and have lived all over the East, New England, mid Atlantic, NYC, Deep South, and TN is my favorite.
