After being put on notice by a national environmental group, state authorities have required Claxton's rattlesnake roundup to get a permit as a wildlife exhibitor, apparently for the first time in its 44-year history. The Georgia Department of Natural Resources issued the permit March 4 for the Evans County Wildlife Club to exhibit live rattlesnakes during the March 12-13 festival. The club paid a $59 fee, provided information about its snake corral and holding pens, and described what goes on there as an educational exhibit.
