We remembered that it had always been rained on in recent years and went prepared with an umbrella. My only negative observation (one shared by others) is that the exhibiting cars have to queue with the 'moderns' and, when we reached the front of the queue, only one person was collecting entry money - it could be speeded up without much difficulty and would also lead to less of the over heating I mentioned previously.
It must be a good, it's one of the few static shows we go to, much preferring driving events.
