Maybe a ride up around Lake Champlain. Amtrak goes up to Montreal & stops along the way. Maybe stop in Plattsburgh and ride around there. Another idea would be to go up to Quebec and do some of the Route Verte. I hear the little towns up there have nice B&Bs. There are good resources for biking the Route Verte and also routes around Lake Champlain. I should think a quick internet search will give you more hits than you can handle!
