the gathering location means nothing; AB has two very large cities with lots of international ties. eventually it was going to hit AB, in the same way that someone with measles was going to arrive in Toronto or Vancouver.

the measles kept happening, constantly, again and again because AB is full of anti-vax communities.

the mennonites got hit hard, but they're not located in huge numbers around the province. dumb-ass anti-vaxers sure are all over the province tho.
