I disagree, if Hartlepool can sell 6,000 season tickets at a reduced price, Bradford can sell over 12,000, Port Vale sell around 5,000 and Barnsley sell 9,000 (after being relegated) then I beleive we can sell a lot more than 4,000 season tickets if the prices were reduced (although I bet half of them wouldn't turn up). I think our cup games in recent years shows that the potential fanbase is there, we just need something major to happen (i.e. a promotion or a takeover) in order to bring them back.
I just wish we had something half way like Bradford with the Flexicard and Port Vale with the 10 game scheme. Apparantly it wouldn't work though
