Last time I was in Nuevo Laredo, over 10 years ago, I had this cute little thing sitting in my lap squirming on junior and trying to negotiate through very broken english. All of a sudden the music goes off, the lights come on and Federalis start walking through the place armed with M16's. I freeze and my new girlfriend says, in plain english, with an accent, "Keep your head down, don't look at them. Everything will be OK". After they left she forgot how to speak english again, Amazing?
Like I said, last time I was there.
