The "private sector" has been shipping through Laredo and Nuevo Laredo for years; this is one of the largest PoE's in the US. Again, the corruption of the border officials (and now the drug lords) makes it not so feasible.
What drives these things is that water shipment is cheaper than rail or road shipment. Even a small savings is important when moving lots of merchandise.
Thanks for the info. I can be sold on the need for better roads and shipping throughout America. I cant be sold on exporting and importing all these vital goods from a country that is as corrupt and unfriendly to America as Mexico is.
Lets improve our ports first.
