(Fayette County, IN)--People who live in Fayette County will see some low-hovering helicopters beginning in the next few days.  Here’s the explanation.  Duke Energy will be using the helicopters and aerial saws to trim trees and other vegetation along power line corridors.  It’s regular maintenance work that’s done to prevent power outages by keeping tree limbs out of power lines.  The work begins Monday and will continue for a week and a half.
