Something For Nothing is the doubletrack that is used to connect many trails, including, Connect the Dots, The Stash, Triple Titty, Man with a Van and the Bears Best area. It is fairly smooth and hard packed and can be fast in sections. The portion of the road that is highlighted is just the section that connects to singletrack. It does continue on at both ends if you feel like exploring on easy terrain.
Although it is an old jeep road, it has a singletrack appearance to it from all of the mountain bike use. If you get over the fact that it is a doubletrack you'll probably have a pretty good time and it will get you to whichever trail that you want to ride.
