In florida it is hard to find anglos on a job site. They are usually going to be plumbers and screen cage monkeys. Masons, concrete, tiebeam, roofers and landscape will be Mexican/Guatemalan/Honduran. Tile guys tend to be Brazilians. Electricians are usually Cuban. At least the Cubans will have La Mica. If the wrong looking van comes down the street the rest of them will be heading for the trees.
My wife says this is really more of a guideline. It goes; "Do you speak english" ... "Yes" "Did you order all the fans" ... "Yes" "Are the guys going to be here tomorrow" ... "Yes" "Did you fly here on the space shuttle" ... "Yes"
