I'd have preferred to be on the grass too but we were next to Aston Martin and right next to the old pits so (and I think others would agree) that there was actually a lot of footfall past the cars (if you visited the national pits then it was on the way out) so on balance it wasn't so bad a place as might be thought.
That said it was quite hard to find when we turned up in the morning!
But, I'd also say that the number of e-types must have caused everything to shift around - so it may be only this year that it'd be like this. The other consideration (I suppose) is that the new track layout means that there is much more grassy area near the bridge available ... but the steam engines also removed other space ....
If your son rode around at Sunday lunchtime then there would've been 4 Lancias out on track !
PS. Anniversarys for 2012 ?
