Two friends and i saw a giant brown boomarang shape in the sky. no lights, no sound, it just glided across the sky slowly. it moved like a low cloud across the sky. a few minutes later i was looking across the pool in the direction where the ufo had gone and there were two orbs of light. i kept looking until the lights started bouncing and all the sudden the ship blasted into space like in the movies. it left tracers of rainbow neon light behind it.
