On May 8, the Bugaboo fire was started by lightning at Bugaboo Island in the Okefenokee National Wildlife Refuge, and soon crept over the state line into Florida (and hence became the retronymed Bugaboo Scrub fire). It expanded extraordinarily quickly, combining with other fires that were already blazing in Georgia, and by May 16 had grown to 120,000 acres (490 km²). By May 22 it had burned 475,000 acres (1,920 km²) in Georgia and Florida. By the end of May had burned. The Florida Folk Festival, the nation's oldest continuous festival, was cancelled for the first time because of the fire. (It was later re-scheduled for November.)
