Well NOW you're in my neck 'o da woods....hm. or Tennessee for that matter? i'll be going to Sevierville for the day on the 28th of September (as copilot without much control over what the pilot does. LOL)

Dare I ask... what in the world is in Sevierville?
You'll want to time that trip VERY carefully as UT has a home game that day and 120,000 people descend... it's a weekly tradition here in the fall.
Course the heaviest away traffic will be from the south that weekend and not the east, so that should help.
