I just wish you guys had a dedicated football stadium to be honest. 20,000 capacity max, fans close to the pitch, would be a much better overall experience. Those egg-chasers cutting up the pitch every weekend doesn't help either.
Failing that though, only good entertainment will attract people back, and that ain't happening at the moment. Of course there are various things you can try in terms of marketing, but in the main, the entertainment on offer has to market itself!
