How do I get into Formula One racing?

[Apteryx]

If you look at my steam account, you'll see that my top game is a racing game. I always wanted to get into racing in real life, preferably F1 racing. Where do I start? I don't mean as a driver or anything, I just want to be a fan of it. Do I just pick a team and freak out when they win a race? Hell, when and where do I even watch races? I have a track for stock cars by my house, but no F1 tracks.

ESPN has a schedule for racing.
