Black Triangle Sighting in Lillington, North Carolina on June 28th 2015 – Triangle shaped with lights

My husband, and our 12 year old grandson left bowling lanes at 10:00 p.m. 6/28/15 in Erwin, NC. They noticed a triangle shaped object with lights in the sky. When my husband sped up on the road, the object either went just as fast or passed him and waited. When he slowed down, the object slowed down. My husband did this on purpose to see if the object was conscious of his movements. This was all on Route 421 heading south from Erwin, NC to Lillington, NC. When he stopped at a McDonald's in Lillington, NC, the object stopped. When he came out of McDonald's the object was hovering over the car dealership across the street (which is well lit). As he progressed South through Lillington, and then Southwest on Route 27 from Lillington toward Sanford/Broadway, NC, object started following him again. Object disappeared about 1/2 way down Route 27 between Lillington and our home. Grandson has a photo and a video but we do not know how to upload it from my grandson's device. We live about 20-25 minutes from Ft. Bragg/Pope Air Force Base and about 1/2 hour from Simmons Army Air Force Base. We see planes and helicopters all the time. This was not a plane nor a helicopter.
