FRANKLIN, Ky. (AP) - It was reminiscent of a "Get Smart" television episode, but instead of detective Maxwell Smart taking the secret elevator to the hidden criminal operation, it was Kentucky State Police.

It was in Simpson County near the Kentucky-Tennessee border. State Drug Enforcement Administration officials say the elevator to an underground chamber was inside a barn and disguised as a shower stall.

National guardsmen and state drug enforcement officers joined state police as 774 marijuana plants were found Wednesday growing in the secret chamber. Their street value was estimated at more than three million dollars.

The operation was divided into separate growing and drying rooms and powered by a generator to prevent detection by the use of excessive amounts of electricity.

Fifty-seven-year-old Cecil Hume and 55-year-old Gary Bullington were arrested.
