Inline skating is my top favortie sport followed by snowboarding. As for more traditional sports, I think its a toss up between basketball and soccer(American).
I ran track in high school - mid distance but enjoyed sprints. That never really carried over after graduation. I still run but only on occasion. I also enjoyed hockey, but it seems to have been a difficult sport to pick up. I tried a new sport about a year or so ago, gaelic football. Now that seemed like a great sport for me
... but again it was hard to get into and pick up. Though I'd hesitate to peg it as a "sport" I'm intrigued with Parkour.
