I'm a G.I.S. mapping professional. I have covered the NH VT border:
Hartland VT , Lebanon NH, Canaan NH, Grafton NH, Enfield NH, and Hanover NH. Routes I 89 and I 93 to Concord, Quechee, Bradford, and Springfield.
I've focused on waterways and major highways tagging, naming, Tiger attribution, and connectivity. My "best" feature was the NH rail trail from Lebanon to Grafton NH.
I've done a lot of post Tiger import cleanup as it overwrote my original data.
