They only had 30K spectators show up for the race. The track was hopping for 35K. The last time they raced there, they only drew 7K spectators I know it won't happen because of safety issues but I would almost bet that if they had ISMA race before them as a support class they would have a lot more in the stands. But most would leave after the supers. The Indy Cars have never generated much interest in this area. Also because of the camera angles you had to look hard to see anyone in the stands on TV

I think they probably get the same amount of spectators when NASCRAP have their Mods/East Series events there.
