NASHVILLE, Tenn.- It’s been over a year since Tennessee passed a guns in parks bill, and it appears parks haven’t changed much. The legislation, which took effect in June 2009, allowed permit holders to go armed in all 53 state parks and 81 state natural areas. Officials say only two gun-related incidents have been reported and neither resulted in violence. Only one major incident was reported when a man carrying an AK-47 was arrested. He was released after determining he had a lawful carry permit.
