Question about the .9 mile Bly Gap trail, just north of the GA/NC border: The Trails Illustrated map shows a gate on the road that leads into Bly Gap trail. If this gate is closed, or if the road past it isn't driveable, then I'd have to walk about 1.5 miles on road, then .9 miles on Bly Gap trail to access the AT. How good is the road (I have a SUV)? Is the gate typically open? Thanks in advance ...
