Supporters of a Shasta County anti-marijuana initiative say their campaign signs are being vandalized. Measure "A" would reinstate a county ordinance passed by the board of supervisors early this year. If approved by voters, outdoor growing would be completely banned and indoor growing would be subject to some of the most comprehensive restrictions in the state. Measure "A" supporters say their signs are being stolen, vandalized, and destroyed in various ways. The campaign says the signs are posted on private as well as public property.
