Some interesting views here. I agree that if its a static show something else needs to be provided, as theres only so much walking around looking at cars you can do! Having great company is a must for me too, the convoy to and from is as much a part of the day as the show itself, but I suppose you have to cater for some who come on their own or a few in one car.
I suppose the bigger and fancier the show gets, the more expensive it is to attend and also its more difficult for the organisers to organise.
