MMA Expo?

In regards to this post on the front page: MMA Expos Coming to the US - No BS MMA and Martial Arts

Has anyone been to this? I had no idea it was going on. Seems relevant since it's also in Toronto.

The Toronto group here seems to be the only Canadian group for Throwdowns. How many people in the group have been to one? The vids I've seen of throwdowns look cool, it'd be interesting just to come observe some fights at least to begin with eh?
