What has four legs, flippers and holds a greased watermelon between its thighs? Why Creative Loafing's FIELD DAY, that's what! On Sat., OCT. 6, Field Day returns to Piedmont Park with all of the events you've come to expect – baseball bat spin relay, dodgeball, tug o' war – along with some new ones, including a boot camp 5K and live music from Sonia Leigh and the Zac Brown Band. The bar opens at 10 a.m. – just in time to rehydrate after the race. And remember, it's all for a good cause as a portion of the event's proceeds benefit the Piedmont Park Conservancy. 5K: $25. Registration, 8 a.m.; race, 9 a.m. Festival: Free. Registration, 10 a.m.; events, 11 a.m.-3 p.m. Piedmont Park Meadow, Monroe and Park Drives. 404-614-1207. atlanta.creativeloafing.com/fieldday07.
