"Travel may not terminate in contiguous territory or adjacent islands unless the traveler is a resident of those areas"

So that would mean if I spend 2 months in the US followed by 2 months in Canada then I should be refused entry to the United States because I've overstayed the 90 days limit! That is news to me and no other agent has ever picked up on that. Food for thought, I'll have to make sure I avoid the US when travelling to Canada!
