No and no on those.
Several places I named fall on the Cumberland Trail route, but last I checked it was not complete and had a lot of gaps.
I read about Obed, but think there was just a short hike up to a point, and maybe something along the river for a ways(?), so kind of dismissed it.
I haven't been keeping up, though. Said I was up there all the time, but wasn't thinking. Until a CO trip last fall got me fired up about backpacking again, I'd mostly been mountain biking the last couple years(even skipped Big South Fork winter before last), and have just gotten back to my "normal" hiking habits of the previous 6yrs or so since then.
