An absolute must!
I can thoroughly recommend Brooklands as a great day out & even if your can only spare a couple of hours it's definitely worth the trip, I was lucky enough to be treated to a session in the original BA Concorde simulator they have there -I am still grinning now!
For me it's the atmosphere that most does it, I feel it coming out of the woodwork, do try to go this year & have a great time ;-)
