A group of basketball tricksters will entertain Iowa youngsters this weekend...but before they take to the hardwood; they're doing a little giving back to the community. Hammer Harrison of the Harlem Globetrotters is visiting Des Moines elementary schools this week. He is talking to kids about bullying and how they can stop it. The event is part of a program called the ABC's of bullying. Hammer says teaching kids how to recognize bullying is an important job. So he uses his skills to catch their attention then drives the message home with fun activities.
