My Aunt, Uncle, and myself witnessed an oval UFO while traveling in Uncles car.

I was a passenger in my aunt and uncle's car and we were either driving to or returning from (I thougnt we were going out to eat and aunt says we were on our way back from) Winston Salem NC, where we were going out to eat.  We were on old Winston Rd. when my uncle slowed the car down,  this got my attention.  There were several cars in front of ours that was also stopped.  Directly in front of us and located above the trees was this hugh UFO.  It was metal in color.  It had round windows all around the craft with light coming out of it, several colors. It was silent.  It defied physics in that it stayed perfectly still, as it set in the air just above the trees, centered over the two lane road we were on.  In moments, it lifted up and dissapeared from our eyes in phenominal speed, again, no noise.  The traffic then began to move on out.
