Sixth-grader Alessandra Williams knocks on the decorated door of her classroom at Mountain Valley Middle School in Mexico on Friday during Red Ribbon Week, a national drug prevention awareness campaign. Behind her are, from left, Melissa Harding and Allie Burke, both of River Valley Rising, Mexico Police Chief Roy Hodsdon and Rumford police Sgt. Doug Maifeld, who judged classroom doors displaying messages about staying drug free. River Valley Rising and the two police departments teamed up to support students participating in the campaign.
