Officials on the field told LBC and Heros, when the original horn sounded for lightening, that their players were to "go to their vehicles immediately and they were to STAY in their vehicles until the horn blew again 3 times, signaling play would resume." The horn sounded at 3:45 pm, alerting players to return to the field. Just because some players returned before they were instructed, does not mean the game starts. You were supposed to stay in your car until the horn, end of story.
and yes, Hero's parents were yelling and screaming at the LBC players as they left the field.
