I'd probably show up if the event was from 10am - 5pm to justify driving all the way, and if there was more to play than just super stock.
That's just my two cents, but there's probably many people that feel just like I do.
Others have said that but not as nicely as you did. The true of it is that our group doesn't really have a base interest for nic. We don't have any nic blasters and only two of us have talk about making a trip to NENO event someday. And the most of ours players are younger age and pretty green to modding so nic is out of there ability and parents' comfort zone. So nic rounds would not be well receive and we have check with a numbers of our players. That being said if some day if our group gets interest enough into nic, we will host a nic war.
This wasn't meant to be directed at you, Lucian. It was just a good time and opportunity to explain before someone say something along the lines of 'allow nic and you will double your numbers' which the opposite is more likely to happen.
