Point Roberts? "Point Roberts also has a small airport and a large marina for air and water access; these two facilities allow direct access to the rest of Washington state without the need to enter Canada." https://en.wikipedia.org/wiki/Point_Roberts,_Washington#Tran... I suppose it might be harder for hitmen to stay low-profile when entering by boat or plane instead of car, but I'd think it's not really going to stop them. It's neat to learn about the place, anyway.
