CHARLOTTE – Robby Gordon roams around his shop about three weeks before his 2011 season kicks off with the Dakar Rally, and he has a group of mechanics working on his Hummer for that event and a smaller group working on a Sprint Cup car for the Daytona 500. The three Dakar support haulers, with millions of dollars worth of equipment, were ready a month earlier and left by boat for South America. The actual race vehicles needed to be finished in a week so they could be put on a hauler to Miami and then shipped as air freight to Argentina.
