flying disk over northern Peoria, Illinois

I was about five and remember it was around the time of the Apollo 11 moom landing.  At some point in the afternoon a group of friends and myself, all aged between four and six, chased a metallic disk flying low overhead in the sky.  I lived on Pinehill Lane in Peoria and the disk seemed to fly in the same vector as the street, roughly north to south.  I remember someone else confirming that there had been a saucer seen over the "Hawley Hills" subdivision of Peoria at the same time, although the "confirmation" I received took place some six years later when my family returned to the area.  I have never reported this before but have never forgotten it.
Time and date are approximate.  PD
