I wonder if I could post something at local highschools to measure interest in becoming peacemakers.
Schools having posting guidelines for their daily announcements and bulletins. Call first to get their guidelines. Also, high schools usually have various clubs that could relate to fighting racism. For instance, at my school we have Stand Up! Speak Up! but I'm sure if you ask their activities director, they will guide you to the right club. The club moderator will tell you the best way to get the students involved. Good Luck and Don't Give Up!
