The Southwest Border Area

Seattle's sea channel brings it very close to the Canadian border. I am noting this because unlike the US-Mexico border. It much easier to get across with no questions asked. For instance the U.S. conducted an undercover test in which they deemed the border, "failing a terrorist test".(Reported by CNN) In which they went through with a duffel bag and no questions asked.
