Take a packed lunch or splash out on hospitality. Official outlets serve grim food and burger vans cost a fortune (£3 for a half portion of chips and an extra £1.50 for curry sauce).
One of the best circuits in the country. Good to watch btcc or cnc barc nw sports saloons or ginettas or superkart at. And very good circuit for a trackday
Make sure you get on the Pit Lane wall at least once during a race, it's a great place to catch the cars racing by and soak up the petrol smelling atmosphere!
Try eating at the Chequersrestaurant instead of the burger vans. The food is much better quality, more choice and, mostly, cheaper. You can also get a good pint there.
