Well, not exactly grown back micely. I was there last weekend for the 6 hour 50cc bike race (yes really!) and while I had the 100/300 lens on I took this shot to give you an idea:-
It isn't a wide enough angle shot but I can tell you that while there is grass it is newly seeded and very sparse. You'll need mattresses because it is still settling and quite bumpy. I know they've put new drainage in but looking at it closely if it rains hard you are really going to be in a mud bath.
Crikey, they've really changed it! The place where the marshall is standing is just about where The Gimp was whipped with leeks over a refridgerated coffin, before he went on and buggered a heron. It was the talk of the campsite for a while and now the spot has been reduced to a marshalls post. Typical ACO, I'll bet there's no memorial plaque or anything.
