At that time i lived in a secluded rural neighborhood with my nearest neighbour a quarter mile away.my wife was not home and i just stepped out onto my back deck which i had just built.the night sky was totally clear and with many stars.as i was leaning on the railing looking to the western sky i noticed something from the east coming into my vision.over the roofline a very large triangular shaped craft appeared.the craft had three lights one at each point slightly set back.one light was blue,one was green,and one was red.this craft was maybe 200 feet above me based on the fact that alot of my trees around my property were 100 feet high.the dimensions were approx.90to100 feet×100×100.it went from east to west at what i would call just a slow cruising speed with absolutely no sound what so ever.it stayed in my vision for approx.one minute and the one thing that i can say that amazed me was that i felt very calm about what i had just witnessed.i told no one,no! t even my wife because you probably know that no one believes you or no one cares.i absolutely know what i witnessed.quite incredible!
