I got one of my best pups from a friend of a friend that lives in Georgia but it was YEARS ago. I have also gotten a great one as an adult dog from Yahoo! classifieds. Once got a pup from a guy in Lakeland. She was BAD. I've gotten an adult dog from a Flyer ad, he was too aggressive. So, no help for you other than to say I LOVE them and overall as a breed think they are one of the best breeds you can get. However, like everything else it depends on breeding group and raising methods. I have worked with Labrador rescue groups and have 2 great dogs from them, but had to send another back, so a rescue group could be the way to go, too. Adult or teenaged dogs from rescue groups can be a good option because someone has spent significant time with the dog and can tell you more about it.
Good luck in your search.
