I'd guess pretty much the same way they manage to fly out of Phoenix, Las Vegas, or LA.
The young males come first and make enough money to bring over the rest of the family.
Much of the money is wired back home, but not all.
You've heard, haven't you, that we routinely find cancelled airline tickets lying on the ground here in the canyons at their layup points? Many of their flights originate in Brazil.
Grumble, complain, moan, wretzle, fretzle, I want my country back NOW! BTTT!!!!!!
Oops, I posted before I read the entire thread, sorry! I had NO IDEA they were now flying in. This is crazy.
