UFO Sighting in San Antonio, Texas on March 29th 2014 – Series of lights, unknown if individual or a part of a whole, slow path of travel, blinking lights, no noise

My family and I with some family friends were at a Neon Dash marathon at Retama Park when at the end of the event they threw a dance of sorts. I was standing at the finish line when I noticed a group of lights in the sky. It began as 1-2 lights until more appeared which is when I began to film with my phone. I felt excited in seeing them and was not at all afraid. I lost sight of them when my son approached me that my he couldn't find his sister. By the time I found her I looked around and the lights were gone.
