Second, and so far only other UFO incident I have witnessed. Two deep orange / red lights were sitting next to each other in the sky. I watched them for a minute or so as I was driving home from my dad's house after a Holiday party. I was on my way to another party - one at a friend's house - when I saw these lights suddenly dip down behind the tree line and vanish. The lights were seen over the south side of County Road 5, over or further west than the Arboretum (A large nature preserve with tall trees which is used by the U of M). The one on the left dropped first, immediately followed by the one on the right. They seemed to come together almost in a V formation as they descended.
