I am about to buy a concert ticket in one of these two cities in October (determined by availability, date, and ease of getting there - Manchester airport seems my best option). While the main purpose is the concert, it is possible I could spend a couple more days if it’s worthwhile. Right now I am about decided on Sheffield because it looks like there are several places in the area I would be interested in.
But I thought I might run it by our England experts to see if I am missing anything. I have based in Manchester before so I don’t think I am looking to do that this time.
