In 1967 our town was celebrating it's bi-centanial, a month long celebration which included several events including a temporary museum housed in an old elementary schol directly behind our house. On the rear of the building was a set of fire escapes leading from the ground down to the ground, just 50 yards away was a base ball field. One evening I awoke and noticed red and green blinking lights in our back yard, I looked out the window and saw something very large hovoring above the base ball field about 20 feet off the ground with red and green blinking lights around the bottom of the craft. The event didn't scare me, and I returned to bed after observing the craft for about a half hour. The next morning I informed my parents as to what I saw, being 9 years old they dismissed the incident as a vivid imagination, until the following day when the local newspaper the Demorcrat Messanger ran a story about the two guards in the temporary museum reporting seeing the same craft the same morning, the night was warm and the guards decided to sleep on the fire escape facing the ball field, they claimed they were awoken by the brightness of the lights of the craft, and eventually it simply rose into the sky straight up and to the northeast until it disappeared about 1/2 hour later.
