Thanks to everyone for the advice, some was useful, but all was welcome!
My lad has been asking me to take him to Le Mans since he was about 7, (when I last went). To put an end to his pleading I promised him then I'd take him when he was older (mum just isn't interested).
"Will that be next year, Dad?",
(cue violins, ) "No son, it's REALLY noisy at Le Mans, and you hardly get ANY sleep, and you wouldn't like it, honest. Maybe when you're a bit older."
"How old, dad? When I'm 8 can I go???"
(And I the little bugger has remembered my response:-
Weeeeeell, I dunno, son. Maybe when you're eleven? IF YOU'RE A GOOD BOY.
And he is, more often than not.
See you there!
I still don't know whether to pitch the tent onthe front lawn of the airport again, it's such a long walk back when the adrenaline runs out in the small hours..... Any ideas for tent sites?
