A friend of mine is a "train driver" or what we used to call a railroad engineer. He told me the other day that the US is the land bridge that China uses to transport their junk to Eastern US markets and onto Europe. According to him their cargo ships are too large for the Panama Canal so they use the US as a land bridge to transport across country to the Atlantic...If that ain't food for thought. I haven't taken the time to fully check it out, made sense from my limited prospective. He said if you see a railcar go by with any container marked HANJIN, your looking at the reality. Maybe I've been in the dark too long or it really doesn't matter anyway. My FIL was a ship's captain for APL, he talked about the global market all the time and most of his predictions have come to pass. Foreign flags run most of the shipping anymore.
