Many people might think Native Americans have been long gone from the area, but a local powwow this weekend aims to show native cultures are closer than one might think. Whippoorwill Hollow Organic Farm, on Ga. Highway 138 in Walnut Grove, hosts its fourth annual Eastern Native American Charity Powwow, "We Are Related," this weekend, June 28 and 29. The powwow combines the atmosphere of a fair, the informality of cook-out and the reverence of a revival as more than 100 dancers, vendors, drummers, musicians and veterans and about 800 attendees are expected to gather for the weekend, according
