I was at my home in San Marcos (near the high school) talking on the phone with a friend.As usual I was standing on my back porch and gazing around aimlessly while chatting. Had I been paying less attention I may have never even noticed what was going on right in front of my eyes. I'd assume the 3 orbs started behind the mountain south of me. The 3 started in a row. If it was one solid craft, I'd describe the first manuever that was performed as a 180. They all continued shifting position like a helicopter escorting high profile persons. They followed a straight line path that went higher and higher until it left the atmosphere and visual range
