Turning your back on your family's school or team?

If you grew up in the South you know that most families have a school that they pull for and that it often spans generations.

At some point in your life did you turn your back on that family school/team and become a hardcore fan of another? A rival or archrival?

If so, why did you do it? Other team was better? Outside influence/peer pressure? Just to be contrary?

NOTE: I am not talking about if you attended another school and changed allegiance because of that.
