Just to be clear, that's not the trail. You missed it. Go back it's on the right. Or from the road the trail is on the left about 100ft in from the road.
I saw two people today do the same thing. Take off into the forest on the logging road. Larose trails use no roads. It is pure single track.
Just remember this is virgin trail so it will present some challenges until it gets used and broken in. The two year old section is shaping up quite nice.
