This is good info thanks.
I wanted to ride across New Hampshire last year but did not get the chance. Looking at the Lamoille Valley Trail and the Cross New Hampshire trail one could have a nice long adventure. One should be able to hook them together. One must deal with I-93, I-91 and crossing the Connecticut River (I think) . I need to look into this more.
