As a community journalist who has covered everything from school levies to murder trials, the most important tool in my storytelling kit wasn’t my reporter’s notebook, my digital recorder or even my video camera. I wish I could say it was an extraordinary set of skills, but it wasn’t that, either. It was, in fact, the glue that held everything together. When used correctly, it opened the most ironclad doors. If damaged, it could take months to repair.
