Was at riverside goin on a walk through the park and the sky was very clear so took a moment to look up. and i saw four bright orange glowing orbs flying about me. they were swaying back and forth coming from the north skies heading south. the 2 outter orbs were spinning and flipping around eachother as the 2 in the middle did not they made no sound. for that i think they are from out of this world. they glided through the sky smoothly. have always been fascinated by the topic but to see it with my own 2 eyes, my gosh! what an amazing experience!!
