Greg,

As usual you are going for the gusto- 42 lights is doable.

I do have one suggestion though- do yourself a favor and avoid Boston at all costs. You should get on I-84 and take that to I-90 (Mass Tpke) to I-495 to MA 110 to US 1 to Newburyport.

This avoids any Boston area traffic and does not take you out of your way. It's the best route to use unless you have to go to Boston. Avoid I-95 in CT for the same reason.
