Was there much traffic? I really don't like such narrow roads if there is any traffic, cars just come around the corner right in the middle of the road.
Second how bad was the gravel, would you do it on fully faired street bike (I see both of these ad ADV bikes). Like a VFR, or your nice SV650?
I do really enjoy roads that run along a ridge, offer great views and make you feel like you're on top of the world.
I tried to get clever to find it on Google maps then realized I could just type in Little Shepherd Trail at it will drop the pin on the road and zoom in appropriately to show the small road.
