Fast flowy machine built ripper opened summer 2021. Steeper than a typical machine built "flow" trail. This is part of the future trail connect to the town of Preston and exit 22. For now it ends at a logging road. Make a right and take the logging road to the East Side Road, Preston Railroad Trail and Silent Swamp Trail.
