Although Wednesday was overcast and a bit breezier than many would expect, that did not deter the kickoff of Main Street Gainesville’s Blue Sky Concert Series. A local group, 2 Guys 6 Strings, entertained the crowd with acoustic covers of popular hit songs and Christian rock. People of all ages convened on the downtown Gainesville square, settling down to enjoy the free entertainment on picnic blankets, lawn chairs and benches.
