These things moved like nothing I,ve ever seen before.I had just joined my wife on the deck and was showing her how to find the north star...for a few moments we sat on the step looking our own ways when right through my line of site two shere shapes rotating around each other moved through the sky from north to south. My first impression due to the G8 summit was that it was some kind of spot lights, but as I tried to point it out to my wife I realized that not only was it a very clear night but that the objects moved in a straight line and very fast as they twisted around each other. My guess is that they were at about 5000-10000 feet, or about as high as an airliner would fly, that is one reason it was not a plane, it was to fast and made no sound at all. If it wasn't a ufo then I have no idea what it could have been,I have seen some odd things in the sky but could always figure out some kind of expaination, I've never seen anything like this before.
