Posted at the top of the Knoll Gas Motorsports Site. Is there a reason other than they want to soak you for refreshments? Gonna be hot all weekend, would be a shame to not be able to bring your own refreshments.

My advice is to get there a bit early so you get a good parking spot. Then you can just run to the car for a cold drink from the cooler. I pack snacks, lots of water & pop, and some towels to soak in the ice water. The parking lot is just west of the stands so it's a short trip.
