Two seven year old kids were roller skating when they observed 2 UFO's flying overhead. They watched as one of them landed and knocked over two concrete pillars in a nearby vineyard. One of these beings emerged from the ship and tapped one of the boys on the shoulder which scared him so bad he fainted. Frightened, the other boy slung his bud over his shoulder and ran home and told their mothers what happened. The moms watched the craft for about 5 minutes before it took off again.
