Event Coverage Bowling Green HRR

Just saw someone say there is no on-site registration this year for the car show? The Pre-registration closed May 14th. I have always just registered on site on Wednesday or Thursday in the past. Does anyone know this for sure or have a better way to get ahold of them. The NHRA has always been lousy trying to get information for this event. You can still buy Spectator passes for the weekend, but I need to be able to drive my coupe in with my canopy and all my gear and bicycle to get around ETC...
