For country music fans in Chicago, there’s no bigger event than the Country LakeShake Festival on Northerly Island. Headliners at this year’s fest include Thomas Rhett, Miranda Lambert and Rascal Flatts—you’ll also get to sing-along to “Save a Horse (Ride a Cowboy)” when Big & Rich show up on stage. In a city where most festivals tend to ignore country music, there’s no better hootenanny in town.
