Looking back at all the clues from the Live Facebook:
1) Duncan: Canadian Military and people who are serving
2) Indonesia: Anti-Bullying advocate
3) Toronto: Coaches and teachers
4) Mexico City: First Responders (could be paramedics, cops, firefighters)
1: It's interesting that he didn't specify we had a team from the military but based on the formula of the other videos, I think it's safe to assume there is one.
2 might be the Argos cheerleaders, as they have a program.
3 is probably Dylan/Kwame because he said: I want to talk about ONE of our teams, coaches and teachers, and we know D/K are both of that.
Is it me or he said at the end of the last video that there would be more Live on the road? Unless the starting line one didn't count, we are already at five, no?
