I like to think of myself as a reporter for the Average Joe. Journalism has become a craft defined largely by city dwellers on America's coasts. It’s time to take it back. I have been an Emerald Triangle resident since 2006 and this is year ten in Mendocino County. Please, email me at if you know a story that needs to be told.
