I've been thinking about this one, but haven't done anything about booking it - I had thought it was a "just turn up" event but you're quite right, they do want prior booking. More info here: http://www.mginfo.co.uk/westcheshiremgo ... ry-booking
I'd probably say it's nearer Chester than Nantwich, though, if anyone's thinking about coming in from North Wales direction. Might see you there Fred.
