State Drug Helicopters flying in neighboring Walker County on Tuesday but they made no big finds. Drug Task Force Chief Patrick Doyle was happy saying, "That means we're doing our job." The team was looking for large, commercial pot-growing operations. The helicopters cruise the skies above the area a couple of times each year. Doyle says they're seeing a new trend — more pot being grown indoors, out of view from the skies. A recent bust in Chattooga County discovered marijuana being grown in a hand-dug underground bunker.
