I don't really think girls are gonna notice that you are from Canada by talking to you. I don't really think they would care if they did. But good luck with that. As for the week you are going, it's a little early. None of the American colleges have spring break until the beginning of March. So chances are, the majority of the girls you see down there are gonna be Canadian too. I'm not sure you are gonna get much out of playing that card. Sorry.
