Tim McGraw has led a pretty fascinating life. He famously had a baseball card of major league pitcher Tug McGraw on a wall in his room — years before he found out Tug was his biological father. However, what he did in Nashville to make ends meet before his mega-success is a little less interesting. He shares with fans in a Facebook post, “Me and my buddy used to go out and clean shopping carts from grocery stores. We would clean them and fix the wheels.” Why leave such an inspiring career for the music biz? “You ever washed a shopping cart in 20-degree weather?” says McGraw.
