The Flowery Branch Police Department will host "Fiddlin’ at the Tracks," a free bluegrass concert and cookout featuring the band Nation & Blackwell on Saturday. The inaugural event will be from 6-9 p.m. July 20 behind the historic train depot at the corner of Railroad Avenue and Main Street. "This will be a family-oriented event so patrons are invited to bring a lawn chair or blanket to relax," Police Chief David Spillers said.
