this factory wasn't created by nafta; it opened in 1928. a lot of the history of the ford era, including the original home of the detroit red wings, was actually in windsor, not detroit.
detroit is a sprawling mess, but it's actually a pretty small city. so is windsor. in recent decades they've been pointed right across from each other.
i think they should convert the ambassador bridge into a pedestrian walkway. this isn't helping.
