"Passports please. Where are you going? What is the purpose of your visit? Do you have any fruits and vegetables with you? Alcohol or tobacco?"Now it is our turn, the border crossers, to engage in the ritualized behavior of nation state boundary maintainence. We act docile, hand over documents, lie about the sesame balls we have in the backseat because they are both contraband and because we cannot imagine that such delicious treats can present a threat to the security of the country (although perhaps this is a failure of imagination on our part since clearly sesame balls must be dangerous to the territorial integrity of the United States or why else would we all be engaging in this ritual of border creation in the first place?). It is difficult not to mourn the end of a relatively open border. Yesterday, as my daughters and I drove up to Montreal for our usual dim sum, I could not find their passports. No problem, of course, since I had birth certificates. As we drove back last night, the border guard waived us through without even glancing at their documents. He seemed friendly and unconcerned about the sesame balls in the back seat. As of today, that friendliness will be more difficult to enact. We can no longer pretend that Vermont is a part of Quebec or that Canada is the 51st state of the United States. We are officially two separate countries and the border will enact that separation ritualistically over and over again each time we pass over it. And many Americans will stop crossing over it. American tourism is already down in Canada and school trips to Canada are increasingly canceled, since not every child has a passport. Over time, the border will become more real and less porous. Its psychological weight will become heavier. And Canadians and Americans will not know one another as well. This is, we are told, security. But I doubt it will make any of us safer.
