As for favourite parts of the circuit... for me it has to be the braking point for Arnage in the darkness of the night. When I first started coming that was about 100m nearer to Indianapolis than it is these days but the effect is much the same. Awesome!
on the same sets of bends, my favourite always used to be Indy corner - on the old spectaor banking before it was removed a few years ago.
then you could see the cars braking for the first left hander and they were so close.
there was no catching fencing between Indy and arnarge then, so it was quite magical at nigt just hanging over the fence with the cars just a few feet away.
those were the days also when you could jump over the spectator enclosure fencing into the woods and walk in direction Mulsanne from Indy corner.
oops, starting to sound a bit like a Grumpy old man!
