1/24/15: As of today there are over 160 entries in for the 2015 SMSC. Because all of you die hards ROCK, we must already CLOSE the 35"Down DOT and the ANY-TIRE classes.  We will be double checking all the info and evaluating where it all stands. But as of today and until further notice, those classes are closed.
