Don't be so sure. I've heard many owners claim that they knew of the only NSX's in their area, when in fact there are others around who don't drive their cars much so there's no way to know that they're out there. That includes one owner in an isolated town of 1200 who was shocked when I told him there was another NSX in town (which I knew from contact I had with the car's owner).
With 2.2 percent of Canada's population, New Brunswick probably has around 15-16 NSX's, assuming the same percentage of Canadian sales of 701. Maybe a few less to account for attrition from wrecked cars, but almost certainly way more than two. Of course, if you live in Moncton, you probably would never run into a rarely-driven NSX in Edmundston or Fredericton (or even Saint John, unless you just happen to be in exactly the same place at the time that the owner goes for a rare drive). Remember, many owners out there just don't participate in the "car scene".
