Central or what?
Hi, Grant told me that the location being central is absolutely vital. He mentioned a Californian meeting that, in the past, had been set in wonderful wooded, coastal bliss but the reasonable distance to it put off very many. A bit further south and the numbers rose substantially.
I and he agree that a wild Scottish location would be superb but it really would ram the numbers down. Central to GB, as Walter pointed out, is needed.
I'd guess that some 100km north or south and a bit east would be accepted.
Finally, after all its Grant and Susan's decision. Where ever it is to be this looks like being a very hard hunt indeed.
