When I travel to SSM to work football, we take the I-75 through Michigan. I've determined that the 6-of-one, half-dozen-of-the-other is Toronto. East of TO and you're better off to drive up around Georgian Bay.
True story:
About 10-12 years ago, my cousin was going to an event at the Joe, and it would conclude around midnight - therefore driving back around 12:15am. The border guard told my cousin that if he hits a red light while driving back to the border crossing, to slow down some, but then to continue right on through when it was safe.
I remember this trivia question from years ago:
What is the most southernly state?
What is the most northernly state?
What is the most easternly state?
What is the most westernly state?
Back then, I was told that there are only 2 states to satisfy answering all 4 questions. I never verified it though.
