The cache is not at the posted coordinates, and should be approached from Old Centreville Road, rather than Route 28. Parking is available at the posted coordinates. The coordinates for the cache location can be obtained by completing the "Tour of Historic Centreville, Virginia" Adventure Lab. The cache is conveniently hidden close to the final stage of the Lab cache. Please come prepared and bring your own writing instrument.
