Hi Andrew

The Black Country is definitely not a daft region! It's a well known region
of the Midlands with a rich industrial legacy encompassing
Wolverhampton,Dudley,Sandwell and Walsall and I've surveyed about 50% of it.
As agreed by the West Midlands mappers a region tag has been placed as a
node in Tipton which is roughly central.  How the tags are getting mixed up
I do not know
I agree that Midlands is not an appropriate tag as a region

Regards

Brian
