Head West young man,
We have the same map and drove every trail on it.
The two trails that go west, toward Walhala get interesting, very pretty scenery. Not much for the hard core just trails.
They become poorly maintained and close in so they scratch the shit out of stuff.
The one that is directly North of M-10 goes all the way to the North side of Walhala,
And there is one just South of the Bridge in Walhala that comes all the way back, jig jog through a couple of roads.
Take a couple colored markers with you and have fun, drive them all.
