i was outside standing on my driveway smoking a cigarette and looking at the stars, looking for shooting stars. actually saw one shooting star minutes before this sitting. as i was looking up i saw a shape, like a boomerang, that was transparent, but the edges looked blurred like a piece of glass. i thought immediately that it was a ufo. it was moving in a straight line from south to north. it was visable less than 30 seconds when it moved out of sight.
