Exactly what segment (percentage) of the booming population of Mexican illegals are you talking about here? Is this the vast majority? Everything I've seen, heard, read concerning California, for example, indicates that we're dealing with families and children (California schools are teeming with non-English speaking pupils). Or do these "adventures" include something more than travel.
They have more babies when they get here... duh.
I invite YOU to produce statistics. I don't need them. I see these stinking pests everywhere I go.
