My only contact with Route 2 is the area that would be a mere day trip for you, Maine, New Hampshire* and Vermont**. But I certainly wish you a great trip, it sounds like a fantastic way to celebrate retirement.

* We enjoyed Littleton - neat restored 1795 mill and thriving downtown, including decorated pianos parked on the sidewalks!
** There's lots of interesting stuff outside of Burlington along the Lake Champlain shores.
