DEERFIELD VALLEY - Twin Valley Middle High School students recently participated in two Sticker Shock events.  Sticker Shock is a national campaign to reduce underage drinking, sponsored locally by the Deerfield Valley Community Partnership.  The campaign is designed to discourage adults from buying alcohol for minors. Participants from the high school placed stickers on cases of alcohol and middle school students placed them on pizza boxes. The stickers read “Zero, Nada, None, No one under 21. It is illegal to buy or provide alcohol for anyone under 21.”
