Looked pretty good from the Kankamagus Highway this last week.
I'm just back from a road trip (by plane & coach): UK => Dublin => Boston (Mass.). Then Boston 2 days (Including guided tours of Boston, visits to Harvard & to Cape Cod)
Then on: => Salem, Gloucester, Rockport => Lake Winnipesaukee, The Kankamagus Highway,=> North Conway, Vermont, Stowe => Montreal (two nights)including a (long) day trip to Quebec. Then leaving Montreal for Ottawa & Toronto (2 nights) including a visit to Niagara (Canadian side) before flying back to UK.
A great holiday, and the 'fall colours' were amazing.
