Chicago Tribune columnist Rex Huppke launched a virtual food drive to encourage his fans - and his detractors - to do good this holiday season. "People shouldn't go hungry," he writes. "That's an idea everyone can get behind." Readers are encouraged to choose team "RexRocks" or "RexStinks" in the virtual food drive, which runs through December 14. Huppke will review the results in a follow-up column.
