Rectangular silver object at the town pool.My girlfriend and I were at the town's pool swimming laps and playing. At 3:15 PM I looked up and saw an object with a silver rectangular structure with a pair of short stout brownish appendages that ran the full length of the rectangle's sides. Within the rectangle were two symmetrical dark gray circular disks.The object had no sound. It did move in a normal flight pattern. Nothing odd here. It flew to the south and curves southeast out of my sight.My girlfriend wears glasses, however not in the pool. The object was large enough for me to track but she couldn't see anything. I am not sure how high the object was, thus I am not sure of its size.I hope I wasn't the only one at the pool to see it. There were 250 to 300 people there, roughly.
