The high school rivalry between Corona del Mar and Newport Harbor produced a hard-fought, entertaining football game on a beautiful September night.  Before, during and after the game, more than a few students were violating the district policy on alcohol and controlled substances.  In her message about punishment, CDM principal Kathy Scott cited parental culpability.  Licensed child psychologist, Dr. Cynthia Baker, has some insights on the effects of teen alcohol abuse, mistakes parents are making and things parents need to evaluate in their own alcohol use.  The Battle of the Bay has started a conversation that every parent should have with their children.
