Classic, who are you to say people that don't go to certain games don't genuinely support their (note the spelling of the word) team? People don't go to away games up north for a number of reasons that have been listed on this thread and probably scores of other threads before.
It is however slightly odd that we don't have a better following up north when other 'similar' teams do, in all honesty I can't think of any reason other than the fact that it is further for us than most (not sure about Pompey and Bournemouth's followings to similar matches?). Most of the reasons that have been mentiond here (money, family, work etc) will hold for any team so don't really justify the apparent lack of support.
And no, I'm not going, as I'm skint and I couldn't find anyone too split the petrol costs with.
