According to article:
After eight or nine hours on the road listening to Gospel music and having a good time, the couple wound up on the Thousand Islands Bridge for Canada.
The Thousand Island Bridge connects New York and Canada. In addition, the article states that he has retained a lawyer from Ottawa, which indicates that the arrest occurred in the Province of Ontario, which does not have a common border with Vermont.
Yeah my bad. Saw Vermont as the US destination and thought they made the wrong turn from there.
