That was pretty much my experience with NEXUS, also. I did my interview in the US, but I was interviewed by a Canadian. They wanted to know why I wanted the card, if I came there just to get the card (also asked that of another person who drove a few hundred miles to get it), if I had property or family in Canada. I also have some pretty exotic countries on my travel list for the past 5 years but they didn't seem too concerned about it.
