I don't follow sports (well, BBing and PLing, but that's it), but I enjoy betting on college football. Thing is, the games are usually up only a day or so in advance, so I often miss them.
I'll bet on any Purdue game. I'll (karma allowing) put 1K on any college football game posted. I also follow Ivy football a bit, so any Ivy League games I'll bet on. ESPECIALLY "The Game", the Harvard-Yale rivalry coming up in the next month or so. I'm putting every k point I have on Harvard!!
