Rock Quarry has three main traps. One is closest to the Grindstone Parkway and Rock Quarry intersection, the entrance to Riback Rd. to the east. The second is the entrance to the new road under construction to the west just north of Riback Rd. The third is located just south of the bridge over Hinkson Creek (if you are going north, this is just as you peak the hill). These traps are used often, since many college students drive this road every day.
