I understand they've been trying to get that trail going for a while.
My favorite trail system in the area is the John Muir trail in the Big South Fork National Rec. Area. One of these days I'm gonna take a few weeks off work and hike the Sheltowee trace, a 250 mile trail that spans most of the Daniel Boone National Forest. Actually, by the time I get around to taking a few weeks off work they'll probably have the pine mountain trail done :-/
