Tri-State Bike Tour - Massachusetts - New Hampshire - Maine

I usually start the Tri-State bike tour from Rowley and bike along the coast (primarily on Rt. 1A) to Maine, then return to the starting point.  I choose to start from Rowley instead of Ipswich because the section of 1A between Ipswich and Rowley, which overlaps wit Rt. 133, can have heavy traffic.
