Ah, c'mon, that's SO outdated in our modern economy.
Rail transport of goods and resources was done by 21st Century Matter Transporters during the Great Clinton Bridge-to-the-Next-Century Era.
Now that GWB is in office, he's dragging us back to the 20th Century with all these increases in that silly rail transport.
Of COURSE I have proof... ya haven't seen any Matter Transporters lately, have ya?!? ;^)
