If it's legal in most states, there wouldn't be cause for this post. It's illegal where I live.
It may indeed be illegal in Watkinsville, don't know, but it is not illegal in all of Georgia. There are legal box bird shoots held in several areas of Georgia, and South Carolina for that matter.
There was a helicopter flying around over a pigeon shoot near here a couple years ago with a cameraman filming out the side of it. One phone call from the owner of the property got that helicopter grounded with a threat to the pilot that if he ever again harassed a legal group of pigeon shooters he would lose his license.
