We were poolside, at the beach of all places, escaping the crowd on the beach. I was watching a plane that afternoon, with skydivers in it, make repeated drops that afternoon. When a few moments after watching parachutes make their decents, i noticed a patch of sky SE of town that was strange because it looked like something moving toward my location. Kind of smokey not really, with a wobble like commotion of speed. A gold, domed disk shaped craft was wobbling at a tremendous speed overhead. I could make out some bulbous formation underneath the craft as it passed, glimmering in the sunlight. I watched it move in a NW direction, the whole incident lasted 20- 30 seconds. I was the only one who witnessed it.
