Going slightly off topic, does anyone know much about the CFL?
I ask because whilst I'm in Toronto in September there's a game on. Of what I've seen on YouTube the rules seem a fair bit different, larger field and huge endzones with the posts in the middle of them, 12 men on the field, points for touchbacks, and being able to challenge for the ball from a punt if you're behind the punter when it's kicked like in Rugby.
