UFO spotted in Maine above a summer campThree of us were sitting on the shores of Lake McGwain at our camp and were watching the water. We looked up into the sky to search for shooting stars. We saw a "star" through the trees that appeared to be moving. After watching it for a minute we realised it wasn't a plane because it would zig zag around the sky. We moved to an area unobstructed by the tree and the object was still there. We watched it for 20 minutes as it zig zagged across the sky. It then started to change slightly in hue to a reddish to a greenish and then back to a yellowish white. The object then began to get larger and smaller as it appeared to be movin closer and further away. All three of us witnessed this event and were quite stunned to say the least. All of us beleived it not to be a star or a plane or a satellite. Although my two companions were skeptics, they also believed it to be a UFO.
