Large Round Liighted Craft hovering over a pond - summer 83 - intersection of Rt32 and New York State Thruway - Platekill NY

On my way home from working 2nd shift  as a computer operator(Summer 1983) - I witnessed a large round craft  hovering over a pond at the intersection of Rt32 and the New York State Thruway. I heard no sound but my windows were shut.  I got a good look at this craft and kept it in my view even as I sped away looking in my rearview mirror.   It was the size of the pond hovering just over the treetops.  There were lights on the craft.    I saw other cars, noticing the southbound cars on the Thruway.  I have looked at sites before looking for someone else who may have seen this.   Through the years I have told my story - always hoping that someone else witnessed this.  It was truly amazing and I thought many times -- maybe it was the lights on the dashboard or fatigue from work - but that is not the case.  (This was right around my 24th birthday)
Date is approximate.  PD
