It takes about a decade to grow a productive pecan tree and a matter of minutes to take one down. A University of Georgia specialist estimates Hurricane Michael's 100 mph winds left 75 percent of pecan crops unharvestable in several south Georgia counties. UGA also estimates a total of $2 billion in losses to the state's agriculture industry. Five months after the storm, many farmers are still picking up the pieces. "On Second Thought" has been following up with growers ever since the storm.
