The woman who starred as Mary Ann on the television show "Gilligan's Island" is serving six months probation as a result of her arrest last fall in eastern Idaho and subsequent guilty plea to reckless driving.
Dawn Wells, 69, was taken into custody after being caught with marijuana in her vehicle while driving home after a surprise birthday party on October 18.
Wells pleaded guilty as part of a deal last month to one count of reckless driving.

In exchange, prosecutors dropped three misdemeanors for driving under the influence, possession of drug paraphernalia and possession of a controlled substance.2
Police reports show she was pulled over by a Teton County Sheriff's deputy who claims Wells' car swerved several times on State Highway 33.
Deputies seized four half-smoked joints and two small cases used to store marijuana from the vehicle, according to police reports.
Defense attorney Ron Swafford says a friend of Wells' voluntarily testified that he had left a small amount of marijuana in the car after using the vehicle earlier in the day.
