Here is what I know: According to the FS Road Map and the USFS Visitors Center just outside Breveard, Black Balsam Rd (FS 816) is open year round from the BRP to a parking area with a pit toiled where the road ends. I've been told though by several people that the road is only open appx August through end of December. The road is not very long (~1.2 miles) and unmaintained. I'm going to try and check it out tomorrow morning to see if it is open or not. If it is open to the end I'll camp there tomorrow night.
Camping areas are located about 1,000 feet off the road and parking areas which works out well b/c you are supposed to be about 1,000 feet or 1/4 miles off the road or parking area to camp.
From what I've seen on the 'official' FS Map and been told by the Visitor's Center everything is 'Go for Takeoff...' unless I hear otherwise.
