The NASCAR Nationwide series returns to Road America at Elkhart Lake this weekend.  The Sargento 200 presented by Menards runs on Saturday afternoon.   Nationwide points leader Elliot Sadler is the pre-race favorite.   This is the third NASCAR event at the road course track.  The past two defending champions, Carl Edwards and Reed Sorenson, are not in the field.  Several other circuit stars will be running though, including Kurt Busch and Danica Patrick who will make her first appearance at RA.  Practice runs are taking place today with qualifying and the green flag drops at 2:30 Saturday afternoon.
