You'll have proper Yorkshire chicks complaining that Leeds and Sheffield aren't in the North West...
But I'm half Lancastrian so I don't care and think it's quite funny to get one over on them
I've voted Leeds for obvious reasons (it's nice and central

), but to be honest I'll travel to any of the suggestions, with Liverpool and Chester possibly being bottom of the list. Manchester and Sheffield are trips I do fairly regularly anyway, so would be absolutely no trouble.
