As far as I'm concerned it has already been agreed that this should be in the North and I've no objection to that. It seems a travesty to me that there has never been a full blown PUG visit to Sheffield so that's my nomination and with a preference for covering the Kelham Island area. The fact I've been there before doesn't put me off at all.
As for dates I would suggest June up to the start of school holidays in July but given that last time I looked Sheffield wasn't a holiday resort that may be debatable.
I hope nobody is going to suggest that Sheffield in Yorkshire is not in the North!!!
