economics and border crossings

I crossed the border into Canada this morning and it took 30 seconds.  The wait to get into the US at 7 a.m. was 60 minutes and rising.  Why are Canadians flocking to the US?  Of course the St. John Baptiste holiday has something to do with the situation, but there is no corresponding exodus into Canada on US holidays.  Even when the US dollar made a trip to Montreal, a world class city, cheaper than a fling in Syracuse for instance, there seemed to be little taste to cross the border.  Are Americans more provincal than Canadians?   Possibly, but perhaps comparing cosmopolitan Montrealers with Plattsburghers is not fair.  I'm sure if the denizens of New York City could cross the border into Canada within an hour's drive, there would be a rollicking cultural exchange going on every weekend.  For my part, I can't wait to get in line later today to spend an hour or two of precious time to return home.
