Queueing was a pain but the "bridge" problem on the site was horrendous and should have been foreseen and a solution found before the event. The exodus from the car parks was mayhem - where had all the marshalls gone ?
The pits had all aircraft tucked up in hangars so could only view from a congested open front. All in all not a very well planned event.
Might I suggest the Mersey as a UK venue - it is long and wide with excellent viewing areas.
