Leaving the house at 5:45 to go to a meeting in downtown austin, noticed a bright light spinning and flashing through the trees to my left. stood there for a few seconds trying to wrap my head around what i was seeing. we filmed the light for about 2 min and once we got calmed down figured out that we should move to the back yard where we have a view over the lake (travis) we made our way there and saw at least 6 spinning bright lights blinking red, green, some blue and red light. the objects bounced up and down, not just a little, but several hundred feet at least if not more. seemingly, no pattern, but random jerks up and down and 45 degree angles as well. i had my camera on and thought i was shooting a video, but was so excited i didn't press the start button even though i saw the images through the camera. really bummed about that. we watched the objects dart around for about 6 additional min. and then had to leave. they were still in the sky, fading in and out of view and bright when we left.
