NH Rt 107
That was a freak day... 72 degrees, bright sunshine. You were on the best stretch of NH 107: between Rt 4 and Rt 28 (where you turned right to go to Alton Bay). That section rolls thru some big hills with sharp curves in every mile.
The next part that you missed continues rolling over big hills. There are many more vista views, the road stretches out much longer without crossing other roads or towns, and the curves are less twisty. We always make a point of either returning from or going to Laconia on 107.
You got a chance to experience first-hand that New Hampshire is the state with the highest per capita motorcycle ownership in the nation. Did you stop in to Merideth HD (just north Weir's Beach, Laconia)? My wife hung out there that afternoon, said that the parking lot looked like a giant bikers festival.
Tomorrows forecast looks more like December. My wife is however optimistic that we will get another day of warm weather to ride in before the winter blows in.
Keep in-touch (my email appears below), it would be great to connect with a V-Rod or two. I'm typically the only one. There are thousands of miles of well maintained yellow strippers up here and the regular residents of this state are used to sharing the roads with thousands of bikers.
I'll post the results of "known good" HD RT locations as soon as I get a chance to meet up with the rep.
