Texas Motor Speedway might say sayonara to six-shooters.  Traditionally, winners at TMS celebrate by shooting off blanks in Victory Circle.  But the Speedway’s president says he’s open to the idea of getting rid of the victory celebration if sponsors have a problem with it.  This comes after the NRA signed on to sponsor the Sprint Cup race on April 13.  The pro-gun group said it was actually fine with getting rid of the revolvers, stating that a more subdued victory celebration would be appropriate.
