Ahh, the USFS Plantation Maintenance and Wildland Fire Access Roads. Those are a whole other level of bureaucracy. Access to those varies from area to area. Sometimes they are left open if they also provide common access to other areas of operations such as bordering National Forests, State Forests, State Parks etc. And sometimes USFS has them locked to prevent unauthorized camping, partying, etc. Your best bet is to contact the State Forestry folks about it first to know if your even allowed to fight fires in there without being called on by USFS, and possibly get a key etc from the Pisgah NF as that is the one that borders BRP in WNC. I used to deal with those all year long back when I lived in MS. Our family lands, as well as the Texas Eastern Transmission pipeline was surrounded by/accessed by/thru the Homochitto NF, and on one side is very close to the Natchez Trace National Parkway. We also have a National Historic Location that is sitting beside an access road in the HNF. USFS left the main access road open, but gated the secondary, and for the plantation "trails" worked with us to build "tank traps" etc to keep illegal hunters from getting down into our lands easily with large 4X4's... Now though with the ATV's that can go almost anywhere, family has had to resort to tire flattening traps on the trails on our side of the HNF line. That and regular patrols with game wardens on our side, and USFS Rangers on the HNF side.
