I suppose we haven't had this debate for a few months.....
My tuppence worth- you can only blame the OF up to a point. Clubs such as Kilmarnock, St Mirren, Motherwell and DUFC are nearer to Glasgow but have significantly larger core supports.
I put this down to 3 things:
First, ICT is a young club and we have to look for the first generation of ICT fans to produce more ICT fans. There should probably be a 'humping' smiley to insert here but this one will do :pram:
Second, Inverness strikes me as a very prosperous place with a large middle class demographic. This leads into discussions of the famous 'Highland Reserve' (which is not something out of a bottle). The four mentioned above are post-industrial places with loads of schemies whose football club is one of the few things to get excited about. The ones who stayed away because of the merger may have numbered only a few dozen but they're the ones who would not have been embarrassed starting a bit of chanting at the TCS.
Third, location of TCS.
