I was in there yesterday with all the family in tow, no car with me this time. I was blown away by the scale of this show also and it looked to be extremely well organised. Weather was great and I wouldn't normally be a steam tractor fan (maybe I was once, not now - would that make me an ex-tractor fan?) but seeing that many of them (20-30?) all clustered together and belching black smoke into the blue sky was cool.
Trade show area was well populated and there was a big area set aside for motorhomes and caravans that had a pile of people relaxing, having a beer and a bbq.
