You can't own exotic hots, you won't get a permit. You'll have to stick to the natives. On a plus note, we have some of the most beautiful copper heads in the nation, native to GA.
Keep in mind, you can't go herping too far from your house. They are illegal to transport unless you have one of the nuisance removal permits. You can get more information from Tim at F&W. I can't remember his last name, but get his email from the website and he'll tell you everything you need to know. He also posts on Craigslist when people post restricted animals.
