Classic saucer shaped object overhead at midday.

While returning from vacation at Myrtle Beach, the 4 of us stopped at a gas station to refuel.  It was a clear sunny midday. The other gentleman noticed this "classic" saucer shaped object overhead.  Could not tell the size.  (ie. large and far away or small and closer) Nothing to compare it too at the time.  It appeared to look very similar to the poster that is now shown on X-files.  It was saucer shaped, domed and had dark areas around the lower part of the dome.  Windows?  It was slowly rotating with a slight wobble.  No sound, no lights, no exhaust trails, nothing.  Since we were close to an Air Force base at the time, I went into the station and asked the clerk to come outside and look.  Since there were no planes/jets around, I figured it might be a military protype.  She said she had never seen anything like it before.  It was moving slowly away.  No one thought to take a picture and by the time I though of using the binoculars, it was far enough away that the detail was no greater than when we first saw it.  Everyone at the gas station was staring and pointing at it.  I have been searching the net for years now to see if there were any reports in the newspapers of that time -- but have found nothing yet.
