Ottawa, Canada to Boston, MA Drive

[crod]

Gents,

I am off to Boston this Sunday and want to take the most scenic drive possible from Ottawa, ON to Boston, MA. I am planning on leaving around 8:00am.
What do you guys recommend??? As I said this drive is all about seeing pretty things so I can take some awesome pictures along the way.
Ideally I want to be there before 5:00pm. As the drive is supposed to take 7:00h I should have enough time to get there by 5:00pm. May even leave earlier if needed like 6:30am.
So what is the most amazing route down there?

It would be indirect, but the Kancamagus Highway (route 112) in NH is one of the best roads in New England.
