US-2 exists for all of about 1 mile in the far northeast corner of New York State from where it enters the state from Vermont on Bridge Road, to where it terminates at the junction with US-11 in Rouses Point maybe ¾ of a mile south of the Canadian border. US-2 then 'disappears' for quite a while before reappearing at Sault Ste. Marie in the UP of Michigan. I suspect that what toidness had in mind was following the Trans-Canada Highway from Rouses Point, NY to Sault Ste. Marie, MI as being the equivalent of following US-2.
