Somebody's gotta steal this idea for Canada...

I don't know if this really is the biggest, but it's probably the coolest scavenger hunt out there. This year's list is pretty mammoth, though apparently, there've been past items that are just batshit crazy.

Clearly, this is an idea worth spreading around, since it seems it'd be really fun to partake in. And of course, I must include some youtubery of this organized chaos.
