I am living in Royal Oak, MD, beside Oak Creek. On the night of June 14, at about 10:00 p.m., I saw lights flashing high up in the nearby trees, the size of softballs. They flashed in separate places amidst the branches, almost in unison, but just for a moment, like bright flashlights being turned on and off. There were at least 15 of these softballs flashing intermittently for quite some time. It was incredible!!!
