You don't have a clue what the people who didn't show up want. So don't speak for them. 

And you were at each meeting to do a head count???

Erin Weir stated that over 200 people came to his town hall meeting on Sept 7th. I wasn't there but can only take his word for it.

However, I did attend the Sept 11 gathering at the RCMP barracks when the minister herself was in town and it was well attended. I suspect that close to 200 people were there as well. Maybe more.

So I don't know where you got your "thirty" from. And I doubt that you do either.
