This is a plea for input to any New Englanders familiar with the area in northern MA and southern NH. I need to bike up to Raymond and back this weekend for a camping trip.

Google maps has a route that is fairly direct but (from looking at some street view panoramas) not incredibly bike-friendly. I'm not aware of any bike trails on that route, but there are probably better roads. What would you recommend?

Thanks in advance for your help planning the trip.
