Here's what's going on today (Wednesday, July 4): It'll be fireworks over the river around 9:30 tonight - look for live music and all sorts of public celebrating around Rousakis Plaza starting at 5. And the Sand Gnats home game (at Grayson Stadium) will, of course, be followed by a display of pyrotechnics. Musically: Whaleboat and Sinister Moustache are sharing the bill at the Wormhole Bar, the Train Wrecks play Molly MacPherson's Scottish Pub, and on Tybee, catch the Accomplices at the Social.
