This weeks Leade rBoard Challenge in CarTown-EX is " The Most Races Won". I like these particular challenges because it's easy to go around various locations in CarTown-Ex and race against the weaker cars. I have dubbed this process as "Picking On The Small Fry". Be sure to race every chane you get to win. There are lots of prizes in various categories to win.Play now! ⇒ http://apps.facebook.com/cartown-ex
