I can tell you that here just north of Atlanta, a few ex-pro wrestlers live. I think some of them might still appear at smaller shows.
They include Rick & Scott Steiner. It's funny, Rick recently tried running for a postition on the county school board, but was disqualified since he didn't use his actual "last name" on his qualifying entry form lol
One other that used to live nearby was Ray Traylor (aka The Big Boss Man)....I met Ray several times, and he was always friendly to speak with. he once gave my son an autographed poster. Sadly, he passed away several years ago.
Finally there's Lex Lugar. He still works out at the gym I used to attend, and you can see him around town sometimes, but he seams to be less visible since the death incident with Miss Elizabeth.
As for Brett Hart (who you first mentioned), I saw him once walking through CNN Center in Atlanta (when WCW had their headquarters there), but I never approached him. At that time, he looked to be in awesome shape, but he appeared shorter than he did on tv - maybe it's the boots he wore? Nevertheless, a great talent indeed.
