How about that border through Windsor-Detroit? The busiest crossing along the Canadian border and with the Montreal mob known to be actively involved in distribution along the border shouldn't the Detroit guys be making the most of this action too. That's where the cabbage is, right?

It was a very busy border dating back to prohibition and the Detroit family made use of it then why not now? there's any number of things going through this border that could bring packages with good tidings for the few wise men of Detroit or whatever it is that is left in the city these days.

The Canadian guys are allegedly involved with the port there.
