Crossing Canada-U.S. border: by bike, hiking, etc.

I've passed through the border crossing by Windsor when we were going to Ann Arbour, Michigan, BikeWriter. Didn't know you were that close to the border.

Another time, I was Sarnia, Ontario where there is another border crossing. A friend who lived in another Ontario city about 30 km. away, pointed out the U.S., just across a 10 metre part of the St. Clair River!
