They are superb! thanks for posting them, I saw my first ever racing at Snetterton in about 1971/2 at the tender age of 3, its is my earliest memory in fact, a thunder saloon race amongst others, and two Porsche 911's winning a race, I was sat on a roof rack on a Mk 1 Cortina eating warm ham sandwiches so it must have been summer
We were up near the old hairpin on the long circuit which I believe is now under the interchange for the A11 now. Great memories! Thanks.
