YouthThink has changed its motto.  The organization that works to strengthen families and guide children toward healthy habits by increasing protective factors with social emotional literacy.  Debby Jones of YouthThink says it is based off the “Challenge Day” concept used at The Dalles High School, and the motto is simply “Do Something.”  Jones says some high school students have created short PSA videos to be shown before the weekly free Saturday morning movies YouthThink will be sponsoring for the next eight weeks at Columbia Cinemas in The Dalles.  The first movie is “The Lego Movie,” with doors opening at 9:15 a.m. Saturday and the film beginning at 10 a.m.
