Start in Canaan and head south on Rt 102 all the way down to Northumberland, VT.
This ride took us through lots and lots of farmland. Wide open fields were on either side of us, and immediately to our left for most of the ride was the river that serves as the border between VT and NH.
I need to qualify the "great". For the first few miles south of Canaan, it's not. It's rough - not dangerous in any way, just rough. But then you hit newly the newly paved stretch and it's all worth it.Since this road follows the river, it's a great collection of tight corners and long sweeping curves. This trip was about great views and fun roads, and this stretch did not disappoint.
Small caveat: most of the tight curves are blind. A few of them are almost on the doorsteps of farmhouses. Only a few, though. The rest is fun.
About 25 miles south of Canaan, where 102 meets 105, you'll find a general store and gas station. That's pretty much it along 102.
Extremely fun road for tight twisties although there are some blind corners so some caution should be taken. Spirited riding here should not be undertaken by novices. There are many passing areas and low traffic. Road quality was excelling in 2012.
