Last time I went was a few years ago and it was very quiet. It used to be big, but I think it's been in decline for a while. They moved the date this year because it clashed with other shows at the beginning of July, including Camperjam, although if the weather is improving, they may find themselves more busy this year due to the good weather we're being forecast for this weekend. Same venue as Bus fest but more chilled. And it's all VWs, not just vans.
Its a good show but its mostly water cooled these days. Dubs at the castle Bug Jam BVF All the same weekend
