What a weird contradiction in your post.
Your excuse for Luton is proximity of other clubs. Have you seen the amount of clubs within an hour of Bolton? Manchester United, Manchester City, Liverpool, Everton, Burnley, Huddersfield, Wigan, Blackburn, Preston, Bury, Rochdale, Stockport, Salford, plus a plethora of non league clubs. There's a lot of competition.
Regardless of that, you've just looked at one or two attendances and drawn a conclusion without any knowledge of the situation. The cause of this has been bad management, over and over again. It's not the supporters. What can they do if they have owners that are irresponsible? They're already boycotting, hence the crowds. They can't do much more to try and force out an owner that lives in a fantasy world, and they can't be blamed for the leach that is Laurence Bassini, whose tactics prevented potential sales of the club to other people going through.
My wife's from Bolton and her brother's a big fan, as are a few of our friends, and it's really sad what's happening to their club.
Whoever the football club, even that lot down the Seven Sisters Road, I wouldn't wish this on them. It could've so easily been us in the 80s/early 90s. Cunts with shit attitudes towards the fans of other clubs have a short memory if they forget what could've been.
