I believe so.. we arrived at 5:07 and found parking right away paid $10.00 Nationals might be a different story.

Yes I was able to find parking for the NASCAR Truck Race at 5:30 pm and the race started at 6 pm. It was $10 for parking and I didn't have to walk very far to get to the track.

Absolutely. I Always get there around 5pm and they have ample parking.
