Hey, hartshorne is my home trail i ride here at least three times a week. i was just out today for two hours. One thing you need to do the next time your there is look for the unmarked trails. there are quite a few and can make the expereince at hartshorne alot better, i mean the park is decent in siz e but can easily be covered in a day. So next time your out check around for a tight single track downhill that starts down near the intersection of grand tour and laurel.
