OK, for the serious answer...
In the UK, most of the shows are so called 'new wave' shows that cater for the non-vintage side of the hobby - either drag racing, or big party tents with music and disco etc. The cost of entry to these shows is usually considerable in order to cover the costs of these 'attractions'. A lot of times these shows attract some trouble during the evenings - just read about peoples experiences of bug jam, cars vandalised, stuff stolen, nuisance neighbours getting drunk and loud till the early hours etc etc.
My experience is that vintage enthusiasts are either older or more settled (with the occasional exception) and these types of shows have little or no appeal.
If you look at Stanford Hall, its a nice setting - there's no big music event, no racing - its like the shows were in t' old days, a nice laid back day out, hence vintage people turn out. Same with Camberg, and Hessisch.
Why doesn't the historic VW show have a better turn out? That I'm a bit more puzzled about, It was getting pretty good when it was at Caughton Court, then it moved and died.
