Then sheriff's narcotics officers bought several pounds of pot in a recent undercover buy. Sgt. Eddie Eubanks says officers traced the pot to a rural residence.
A search dog fell through a camouflaged trap door leading down to a full-length school bus buried 8 feet under a backyard tool shed.
Deputies seized 68 plants, each 4 feet tall and weighing about 35 pounds. Eubanks says the plants were worth about $40,000.
Three people have been arrested.
