Trace Adkins is pretty much an open book ... In fact, he's written a book, 'A Personal Stand,' that reveals some painful (and some funny) personal stories. But he's perhaps never been as candid as he is on GAC's 'Backstory.' In Wednesday's (Oct. 14) episode, the country superstar opens up about everything from being shot by his ex-wife to being in an alcohol-fueled accident. Watch a sneak preview of the show after the jump, and be sure to tune in to 'GAC Backstory: Trace Adkins' this Wednesday at 8:00 PM ET on GAC.
