Rangers.
Since we were trapdoor-ed into the lower leagues, I've had an aversion to attending away matches with the same regularity and gusto that I had previously. Essentially, I'm disinclined to line the pockets of our haters these days, though I've felt compelled to go to Pittodrie and Easter Road on occasion. What can I say, old habits die hard. To fill the 'away day' void in my life, I started following Pollok as they were my local Junior outfit. I 'support' them in the sense that I pay money to watch them home and away when their games don't clash with ours but in reality, I just have a soft spot for them.
Rangers come first, second and last. Nothing else matters. In the now dim and distant past, like many other posters on the thread, Scotland was a non-negotiable and have been to Wembley etc, etc, following the national side. Nowadays, I'd rather hammer a red hot six inch nail down my Japanese's eye than watch them. The Tartan Tadgers would put you off following football. Period.
