Grateful Dead music lovers will no longer be truckin' down to Shannon County for outdoor music festivals if three law enforcement agencies get their way in federal court.

On Monday, the U.S. Drug Enforcement Agency, the Missouri Highway Patrol and the U.S. Attorney's Office filed a joint complaint in the Eastern District of Missouri asking to seize the 350-acre Zoe Farm, alleging rampant drug dealing and drug use at events.

According to its website, the farm, called Camp Zoe, is located 150 miles southwest of St. Louis near Salem and hosts a popular Grateful Dead festival call Schwagstock every year, as well as biker and pagan rallies and individual concerts. Once a popular summer camp for kids, the property was purchased in 2004 by Jimmy Tebeau, a member of the Schwag, a Grateful Dead tribute band. He opened the grounds to recreational camping and float trips and began hosting the festivals soon after the purchase.

In the complaint, officials said investigators spent four years monitoring and interacting with concertgoers on the farm, witnessing drug use and completing open drug deals with participants during events. Officials allege that the owner and event operators were aware of the activity and "took no immediate action to prevent" the sale and use of cocaine, marijuana, LSD, ecstasy, psilocybin mushrooms, opium and marijuana-laced food.
