I was at a park not far from my house trying to see a meteor shower. I noticed alot of stars out and saw what I thought was 3 stars in a triangle pattern in the sky. After a while the lights began to move. They were going straight for a bit and then began slowly going side to side. They moved left and right and up and down. Then after a bit they light got dimmer and smaller then were gone. I tried to use my camera to get a video but I guess it was too far away because it didn't catch it. I have also have 3 other instances in my life where I saw UFOs also. Once when I was about 6 or 7 and both my parents witnessed it at a drive in movie theatre. Once when I was 13 while looking through a telescope. And once last year at my mother's house in Sharon PA. These three instances were all different though.
