I'm probably wrong on this, but that looks like the gravel road going through the national forest. It's a good ride and decently well maintained for a gravel road. There's several gated logging roads that you can ride if the gates are open. Most don't lead anywhere but they're fun enough. Word of warning, the rangers there are not what I would call motorcycle friendly. I rode there with my Dad last year and we were stopped twice and told that our bikes would be confiscated if we were caught on any closed trails.
