On December 16, 2013 at around 7:30pm 3 explorers were sitting on the East side  underneath the 101 freeway overpass at about 7th Ave. Up on the embankment looking west. The explorers were sitting directly in center of the bridge underneath the freeway. The darkest part of the bridge is of course the center. Dim light were luminating the sides of the bridge on the Eastern and Western sides. A full moon was present that night. As the three explorers were conversing , one of the explorers noticed a dim mass of light, oval in shape and about 15 feet long and 8 feet wide,traveling  In a North South direction right in front of the three explorers. It was moving at a slow steady pace. They all paused and starred at the light and looked to see where it was coming from. As they looked in fright the three explorers all got the chills and had a feeling in their gut that something was not right. Til this day they do not know what it was.
