A host of big-name sponsors running the gamut from the EPA and the Greater Cincinnati Earth Coalition to Duke Energy and even Wal-Mart (and plenty more) have pooled their resources to bring Cincinnati yet another all-day environmental extravaganza for ’09. Sawyer Point is again party central for this year’s Earth Day celebration. Those seeking family-friendly fun will find a petting zoo, rock-climbing wall, a “green” fashion show and many more attractions to occupy the kids. Hands-on exhibits and information booths from local environmental groups, businesses and agencies will give the more information-starved grown-ups among us something to do. And, of course, there’s one major attraction the Earth Day fest traditionally offers that’s sure to please everyone: live music. Highlights include contemporary folkies Wild Carrot and the Roots Band, who perform at 12:30 p.m., and “infamous trashgrass” practitioners the Rumpke Mountain Boys, who take the stage around 4:30. Earth Day at Sawyer Point runs from noon-7 p.m. Get more information here.
