Did a count yeaterday and there was 452 not renewed, which is odd as if they are going on tickets by the time they are available they may be squeezed out the north.
But probably a combination of changing circumstances, the under 4 free seats going, people moving, some not able to afford to renew etc.
Looking at the Blackburn ticket site their previously mostly full stand behind the goal bar yhe front bits now has a similar pattern to ours, scattered seats etc.
So I'd imagine it's fairly normal, if not a little disappointing when people don't renew.
Price rises at this time and a bad summer dont help.
