The more the merrier,
I think this years NC topped out at 520 ish entries. Lets see that be even bigger in 2012. I think it could happen with the race setup it sounds like will be used. Doesn't mean 520ish racers though. Still I think the entry count could be better than this years.
The wow factor for me is the 3 track setup, with 3 different scales all running at the same event. They are shooting for the stars and then some. Can't wait to see what "The Dirt" crew comes up with for all of that.
