While sitting in traffic on the mid- point bridge, I noticed a small dark object about 1000 yards away above the trees. I was on the phone with my wife and I told her there's something on the tree line. As I slowly made it over the bridge the object got closer. Once I made it over the bridge the object was close enough to see detail. It got t to the point where it was right in front of my car about 200 feet off the ground. It was wobbLing slowly as it drifted in front of me. It was only moving maybe ten miles per hour in a roughly SE to NW direction. The object had a large central section, similar looking to a soccer ball, but not round, slightly angular. It was a dark gray/black color but the sun was reflecting off of the top of the east side of it. It had three legs, all segmented, maybe three segments on each leg. They appeared evenly spaced. It went right over my car then I lost sight of it as the traffic started moving. I'm going to make a computer drawing of it when I get home, I just wanted to get this in while it was fresh ibn my mind.
