white orb triangular craft followed us.I was leaving the house to take my girlfriend to work. As we got to the end of our street I looked directly across the street and up. About 50-80ft above the tree I saw three white orbs in triangular formation very close together. It moved suddenly then stopped, it then shifted shapes and took on a form similar to a helicopters light pattern. One of the lights even changed to a flickering red. It started moving to our right before we even turned. I proceeded to take my girlfriend to work which is in the same direction. Never taking an eye off it I turned as well. I didn't put my blinker on for my next left turn. My gf keeping an eye on it the entire time, noticed that the craft turned back to our direction.We really got freaked after this. Once the craft was back over us it started circling our vehicle as we went down the road. It was following us. At one point it shifted back into the all white three orb triangle, then back to the helicopter form before the nex! t main road. We turned off our normal route and into the Wal-Mart parking lot and parked for about 13 mins watching it make a wider circle around the area. We left the parking lot and got back on route. Back on top of us circling again making every turn we make.My gf tells me she's not going to work to just keep driving. We end up across town and rush into a friend's house. Watching his surveillance cameras we watched the craft split into sections and one stayed visible on screen flickering and moving slightly. We stayed there about three hours before we got the nerve to leave. Once we came outside the craft vanished. We made it home with out being followed. As far as we know.
