At 12:15am on July 31, 2014 I walked out onto my north facing deck to cool off, and noticed how brilliant the stars were, and then after looking all around I saw a flashing/blinking star shaped light, it was going first down and then back up and then making a diagonal line towards the east and then back up to the same point on top, then back straight down and then back up again then moving straight across eastwards and back again and then another eastward diagonal, then straight up. It did this many, many times before I saw another coming to the treeline that looked the same as the first one, as if they were moving/making a grid, one just below and to the west of the first one I saw. They were star like in shape but emitted flashing colors of red, green/blue and gold-ish lights, I watched them for almost an hr and they appeared to be moving north, slightly east all the while doing this same like grid pattern, getting smaller as they moved more northward. Very cool..Stars and or planes or satellites do NOT move in this fashion..I do believe I witnessed a UFO.
