The ninth annual family-friendly music and outdoor festival HemlockFest is taking place this weekend near Dahlonega and will feature about 20 bands performing a variety of styles ranging from bluegrass to blues. Produced by the Lumpkin Coalition, a nonprofit organization formed to facilitate projects benefiting North Georgia and Lumpkin County, the event is designed to raise funds and public awareness of the problems with the state’s Eastern and Carolina hemlock trees, which are being killed by the parasitic insect hemlock woolly adelgid. “We consider the festival family friendly, but there is beer and wine for the adults,” Lumpkin Coalition Chairman Forest Hilyer said.
