With the Barren Fork River running through the city, river-related activities are on the rise in McMinnville.“There are a lot of people enjoying spending time on the river,” said McMinnville Fire Chief Kendall Mayfield. “At some point, we are going to have an emergency situation. I hope we don’t, but I want my guys to be prepared just in case we do.”Mayfield has had firefighters, who are also first-responders, practicing water rescue exercises at Gilley Pool last week.
