The irony is that since then I've crossed the border 12+ times a year and the experience is always pleasant (now I enter as a Canadian citizen for either vacation or a short business trip). One would think they'd have preferred me when I paid taxes there (and by the virtue of being on visa, they knew a lot more about me).
American go-getter attitude abroad seems to be a winning combination.
Even Singapore has been raising the bar for entry lately. We may see in our lifetimes a world where one can only easily migrate to third-world countries.
I'm confused as well: which path in the system should be credited as most wrong? The intersection of you being Canadian, brown, and in a better profession than customs agents seems rife with opportunities for them to F you over.
Hell, I'm a white guy and despite this privilege I ass-kiss too much whenever I travel because they can decide to do the same to me. Not nearly as likely, but since we gave up our rights to opaque government security services, who knows. Not to be US-bashing, I do the same when I have gone international.
