For me, since the opening game of the 74/75 season, no other opponent comes close.
The tear ups, the doubles, the heartaches, the piss taking (even more apt now they've got Blue Rinse Hilda in charge!).
There's something about our meetings with them which I've (mostly) enjoyed and always look forward to days in advance of the game. Don't feel the same about any other club.
AT LAST, a supporter with a sense of what this is really all about.
