During Tuesday’s Shasta County Board of Supervisors meeting, the board may adopt a code of conduct. Such a set of behavioral guidelines has been suggested for a long time by members of the board as well as the public. Nothing, it seems, is without controversy in the supervisors chambers, not even good manners. There are two competing codes of conduct that will be discussed. One of them is sponsored by Kevin Crye and the other is sponsored by Mary Rickert and Tim Garmin.
