I would expect a number between 35-40 (just a guess). Over the first 3 Smackdowns a number closer to 40 has been present on the opening night and as attrition takes its toll along with the qualifying rules for Saturday coming into effect the field dwindles slightly.

However IMO car count doesn't matter because the best NW drivers in the country will be there, at perhaps the finest 1/4 track in the world, it doesn't get any better.
