Sighting of a disc shaped object by three people.

This sighting occurred about 400 yards from the intersection of Amboy and Woodbridge Avenues, in the southwest section, by three prople at a nearby gas station who saw a light go down in the woods nearby.
They drove down Woodbridge Avenue and turned off a service road where they saw a saucer shaped object in a field.
They left and reported it to the authorities.  For about a week they spoke about the incident to friends, who later said to other people that they had been serious about it.
Some days later, I drove by the area, and the army had a flat-bed truck by the side of the road and had roped off the woods around the entrance of the service road there.
Afterwards, when I went walking in that area, I saw a crushed, burnt area about 100 feet across in the shape of a circle in a field.
