His Story
"Larry and "R.M." are the best of friends: these two can usually be found raising Cain and takin' names on Redneck Hill. But despite their rowdy nature, they are true southern gentlemen, and dead serious when it comes to racing. They know the stats on every team, which is useful since they've always got a bet riding on who will be the next Piston Cup champion."
