From the movie “The Burbs”:

Carol Peterson: Where are you going?

Ray Peterson: I can't walk anywhere without you asking me where I'm going - I'm going to Paris, France, okay? I'm going to Banff, Canada, alright? That's where I'm going.

Carol Peterson: Are you taking the dog?

Ray Peterson: Yeah, yeah, I'm taking the dog for a walk.

This was my only exposure to Banff Canada as an 80’s teen. Apparently, due to a writer’s strike, lots of the lines were ad-libbed by the cast. Perhaps Tom Hanks has a soft spot for this magical place.
