If you build it, they will come. That’s just what the Warren County Chamber of Business and Industry was hoping when it decided to create a brand new mountain bike trail system in a portion of the nearby Allegheny National Forest in 2015. Fast forward several years, and the trailhead parking lot at Jakes Rocks is full of cars with bike racks every weekend. Mountain bikers flock to Warren, Pennsylvania to experience what will soon be nearly 30 miles of exceptional singletrack constructed by Dirt Artisans.
