Grace McNeilly, a Gainesville resident, started having digestive complications when she was just 3 years old. Her family took her to the doctor to see what was wrong and, after numerous tests, found out she had cystic fibrosis. That’s why her father, Michael, is passionate about making people aware of the disease and raising money for research to find a cure. To do so, he and Doug Dichting, an investor in Left Nut Brewing Co., will be hosts to “ShamRockin’ for a Cure North Georgia” at Left Nut at 7 p.m Saturday, March 10.
