I thought I'd jump in here real quick!
In late August (can't remember the dates exactly), on Powell Street in Gastown (I think), there were 1950-1960s model cars with California plates, and the street was dressed as San Francisco.
I was also visiting Vancouver early last month, October 8th, 9th and 10th I believe. Somebody was shooting something near the intersection of Homer and Robson Street. The street was lined with cars with New York license plates and yellow taxi cabs.
If anybody has any information on these, that would be awesome! I'm merely curious.
