No food or bev carried in. The parking is reasonably close so we pack a cooler and dig into it when track prep is going on.
They sell basic track food at a good price. Would expect top row seating to be reserved so go early and leave a jacket in the seat you claim so you can walk around and not loose your spot. You'll probably need the jacket by the late heat races as they will open the place up some to alleviate the fumes. Have fun and enjoy the show!
