I forget which crossing it was exactly. Might have been Windsor or might have been farther north. We drove several hours before switching to the shuttle in any case and didn't get out to look around on the Canadian side of the crossing.

It could have been a biased sample. I mean, for all I know, one very obese family just happened to get on that same shuttle rather than it being a random sampling of what people were like in that area. Hell, they could have even driven several hours to get there themselves and thus didn't represent the local population at all.

Could have been bias confirmation rather than culture shock.
