I believe the disappearance of trees at the bottom end of the circuit is mostly down to one nutter and his box of matches, numerous forest fires down there last summer.
Well, if the local info is anything to go by, they were using tennis balls full of flammable liquid and fuses, firing them with catapults. The loss between Mulsanne and Arnage is bad, but the other side of Mulsanne was 230 acres.

Incidentally, they are starting to replant apparently, or so it said in this week's paper.
To finish, hope the weather gets better. It is 15C and has been absolutely hissing down since yesterday evening. Hail, thunder, lightning - you name it , we've got it. I can hardly hear myself think.
