I have been crashing a lot in the whoops lately and I’m not really sure what is going on.“We will keep trying to get better. We have some other things going on now that I am excited about. It’s a bummer year but what doesn’t kill you makes you stronger. I appreciate all the support I’ve had this year and we’ll step it up.”Overall, Stewart finished on the 2011 podium nine times in 17 races, including five wins (Phoenix, Oakland, Anaheim II, St. Louis and Seattle).
