You're probably right. I've not driven / traversed that part of it, but I know OD Guin Road (FS321) is maintained at least as far south as Bayou Camp Road, and likely beyond to FS360. One of the roads (maybe OD Guin?) basically ends as a road in a small clearing, with nothing but a trail on the far side. But I'd have to drive up (hour+) to confirm that. Thanks.
