I feel like my love of Motorsports is so similar to my love of Football.
Football, or soccer, being a sport that isn't popular here, but was brought to my attention thanks to the '94 World Cup and my Dad getting into to, and from then on out, I kept watching the World Cup...Years later I got introduced into European club football, and my life was changed. I feel in love and find club football so much better than World Cup, even though the popularity isn't there (at least here).
Grew up with Nascar, yawn, and a few years ago got introduced to F1, and now I'm finding out about endurance races and again, I feel like my sports life will never be the same. This is absolutely brilliant.
