That's around the time of bike week in Laconia not too far away. There's the Kancamagus at least and probably a lot of other great area rides. I got my HOG tour book about a month ago and only glanced it. I can check it later
From Acworth pick up rte 10 to Newport, then 103 to Newbury, left on 103A to rte 11 to 4N in Andover, pick up 104 in Danbury, this will take you to Laconia Harley. About 75 miles. Nice ride in the fall.
