well, for one thing, there's a whole lot less hassle from cops or criminals than you think. Especially down in, away from the border, and also, like up here, away from the big cities.
and it's a lot cheaper, not just a little.
and if you know just a little of the language, it can be very pleasant down there.
but as much as I enjoy traveling to foreign parts, and I really do enjoy it, I always feel a bit out of place and off balance until I get back to the good ol' USA. Even in England and Scotland, it's wonderful, but it's not home.
