Slow moving classic disc 50ft up

Date is approximate(I chose this date as a very similiar report has this date) also actual city was West Hollywood which is a surrounding area of Fort Lauderdale.
I was about 12 or 13 at the time.  I was riding my bicycle up and down the street in our apartment complex, which was approx. 1/3 of a mile long.  From the North end of the street a "classic flying saucer" came hovering over the tree line about 40 to 60 feet high. It was like right out of the movies, a metallic disc with colored lights rotating around it (I'm colorblind so sorry I can't tell you the colors).  Diameter was about 30 to 40 feet, 10 to 15 feet in height symetrical top and bottom.  It made no noise.
At the time I was not scared, but only interested and I followed it from one end of the street to the other.  I literally road my bicycle under it the entire length of the street (1/3 mile) which it strangely hovered directly over seeming to follow the road.  I was easily able to keep pace with it so I estimate its speed at no more than 15 MPH.  At the end of our street I stopped and watched it continue on at the same pace.  Because of its low altitude it disappeared from view before to long.
At that time the Goodyear blimp was a regular sight in Lauderdale and TV/movies portrayed UFO exactly like this one; so even at that young age I was skeptical, thinking that this was to good to be true.  I figured I would hear of a hoax or some explanation.  That never happened.  Now as I've grown older I realize the importance and significance of such a "clear and close" sighting.
 I will try to send(email) more info(map and illustration), Thanx
