Ride those, they all connect and you can't get lost. About 10 miles of trails, hilly, some technical. Very muddy when it rains.
"Take UNCC exit off I-85 and turn left at the second light by the hospital. A security guard from the hospital told some riders not park on hospital property or ride our bikes on hospital property. He was very nice about it and said this was due to liability. He ask that we park up in the grassy area across from McDonalds or park at the library. There is a trail at the back of the library parking lot.
