I'm a City fan in my mid 30s who grew up in north Bristol, and I have more mates who are Rovers fans then City fans, as a result.
I remember the late 80s and early to mid 90s, and our inability to beat them for a number of years. As a result, they will always be our rivals to me, if not literally because, you know..
