I've honestly no idea how I'd feel if United went. I'd have to wait until the dust settled and see how I felt.
Given where I live now, the obvious thing would be to follow the Binos but... meh, it wouldn't be the same. I'd probably find a different Saturday hobby.
If the majority of folk feel like me, all we'd need is for a couple of big-to-medium sized clubs (Hearts, United, The Dees) going to the wall for Scottish football to go to the wall too.
