Hiya, just had a look around and there is a link for information here

looks like a good show , we tend to do at least one each year Gt Dorset steam fair being my favourite , we camped there for a week last year even though the show didn't start until the Wednesday , year before we did Wellend st fair but the Gt Dorset is the best by far , would like to see this one but booked in elsewhere already .
