Welcome to The Weekly Dirt. This week "Dirt" comes to you from the site of the Cajun National Enduro near Alexandria, Louisiana, where factory KTM rider Russell Bobbitt got his second win of the year. It was a close one, though, as defending series champ Charlie Mullins was breathing down his neck heading into the final test.I may have mentioned before that Russell Bobbitt had a bad year in 2010. After winning three-straight national titles, the Georgia rider managed only one national win all of last year and finished out the season in third overall. Certainly not where he wanted to be. According to Bobbitt, it made for a long winter and he thought every day about what he wanted to do differently in 2011. At the 2011 series opener in South Carolina, Bobbitt came in fit and ready to go and he walked away with an impressive win. He carried that momentum over into Louisiana, although Charlie Mullins and Cory Buttrick were laying in wait.
