I've been to the Festival of Speed a few times, beginning in about 1994 - not long after it all kicked off. It is magical! The atmosphere at Goodwood really is something else.
The Revival meeting has a similar feel. If anything, it is sensory overload - too much to see, hear, smell...

But what an experience!
I'd love to go along this year. The Can Am cars are some of my very favourite. However, other factors are likely to intervene.
