I read your post mate. You're saying that if the club announced ticket availability more frequently or if this info could be accessed in a easier way, more people would come. It's a terrible excuse as if you are thinking of going, it's quite simple to find out if tickets are available. The easiest is to call the ticket office. When someone answers, ask them if there are any tickets available for the game you want to see. If they say yes, tell them you would like to book. If the answer is no, thank them and try again next time.
Hope this info helps you and anyone else who doesn't go for this reason get to more games.
