Ooops! Tried post to answer, but hit the wrong key!
To continue, I asked this question at Berwick two weeks ago, and the official reply was that it won't be ticketed, but that the Berwick promotion have no control over pricing or admissions.
The event is an FIM meeting, being promoted by the BSPA on behalf of the SCB!
In effect, it is a 'shared event' like the PLRC is at Sheffield.
The Berwick promotion don't set the price nor do they get to keep the money!
Which some might think makes their energetic efforts to promote the event all-the-more commendable.
