1 of 3 UFOs followed my car after we watched them hovering for a few hours.

During the summer of 1974, two of my cousins came to my home upset and frightened, saying their car had just been "buzzed" by a large object with bright lights. They were afraid to drive the rest of the way home alone, so I followed them in my car. When we reached their home and looked to the east, we saw three objects hovering above a field behind our grandmother's home.
 They were in a triangle formation, with two on top and one on the bottom. We sat on my cousin's porch and watched them for a few hours. During that time, every so often they would swap positions, reversing the triangle. They had mainly white lights, but those changed periodically to orange.
 When I left, one of them broke away and stayed parallel to my car the entire length of the road (about a mile). I turned right, and it did the same. It remained beside me, just above the trees, until I met a car a half a mile later. Then it did a 180-degree turn and followed that car.
 My cousins said the other two left in the same direction I drove a few minutes after my departure. We never saw them again, but there were other reported sightings in our area that summer.
Source of report indicates that date of the event is approximate.  PD
