I was camping in the Upper Pennisula of Michigan on it's East Coast on the Keweenaw Pennisula with my dad and a family friend when we saw this real bright light on the lake near what would be the horizon, we at first thought it was an Ore Boat, but then the light shot straight up in the sky. The light (orb) at first was a very big white light (much bigger than a star or aircraft)but when it reached altitude it started to change colors from white to red to green, it started pulsating faster and then little lights that where white started to shoot out of it at the same time (3 of them) they would then shoot back to the main white light and join with it) then the main white light (orb)would just blink out and then reappear in another posistion. All three of us watched this for probably about an hour, finally the bright white light just moved off from East to West and disappeared. Also my dad took some pictures of us sitting around the camp fire on the beach and there are weird misty looking things around our heads (it is not smoke, the wind was blowing the other direction).
