I'd really fancied going to this having missed out on the lotto draw last year, but on closer examination of Longleat on the OS map and considering the stated 1 mile muddy trudge to the viewing areas, I decided to give it a miss - based on years of experience being stuck getting in/out of F1 GPs.
Shame, but they either need to strictly limit tickets to say 20,000 or choose a different venue.
It still makes a great TV spectacle. Those of you complaining really should get a hard-disk video recorder, then you fast-forward to the interesting bits through all the guff/adverts at 32x speed. I've used one for years and consider it essential to watching any commercial TV.
