Travel Note
If you haven't spent much time around Middle Tennessee, make sure to account plenty of extra time for traffic. It can be congested for no apparent reason and change at the drop of a hat (just like the weather), and nowhere is immune. So if you have somewhere to be, check a GPS well before you leave and know you might get delayed en route.
