wow - thank tnjacke - looks like i need to add a couple of nights to knoxville and gatlinburg! we're doing the loop - down 75 to chattanooga, back up to knoxville/maryville, over to gatlinburg (all interstates where possible).
we're actually making the trip to see if we like the Maryville area. DH has read that it is a nice retirement area. :)
