A French family who through paddled the trail last summer is slowly updating their blog and are up to Spencer Stream in Maine. Their posts share the rough spots along the way as well as notes of well-signed sections. Look for your section of the trail to read the Bognet’s comments about it. Maybe it will be useful and maybe it will make you smile: https://northernforestcanoetrail.wordpress.com/. Thanks for being an NFCT Trail Maintainer!
