My best guess is that this is a decent campground for any race except NHRA Nationals. Generally clean bathrooms and showers. It is just across the streer from the Lucas oil raceway. That is one of the only benefits.
Now if you enjoy being overcharged and consistent pricing changes at the last minute (2 weeks before the event) then this is your place! Just wait!! Each year there are changes and price increases that you don't find out about until the last minute! Exciting, right!?! So don't bother planning/saving money before hand. Take out a loan and you'll be just fine.
This is not the first time that they have increased pricing at the very last minute. My family has been going to this Campground over 20 years and over the last 10 years the prices have doubled if not tripled for cmaping and permits. This used to be a fun place to go and enjoy camping, socializing and racing. Its all about the money now and how much they can squeeze out of their customers. Huge police presence which is uncomfortable instead of reassuring. They have also now began charging additional camping costs for kids 10 and up. The woman's restroom only has two occasional flushing toilets too...so it is awesome when one is out of order. Save your money and get a hotel room. Way better deal.
