Thinking father west than south, Chris.
Problem with the Midlands show since it moved from Donington is that it's in the middle of nowhere.
Timing is also relevant. For years we have been told by organisers that a summer show is out as people are away on holiday but I don't see this with the ME fraternity. Most are retired or dead [ or close to it ] and they can take holidays at any time.
Harrogate is beginning of May then Bristol is next in late August, nothing in between.
