I've mentioned before that nutcase nadin, as a Mexican, is highly qualified as a shit expert. In Mexico, it's everywhere. Encrusting fresh vegetables, in ice cubes, in high concentrations in tap water, and pouring untreated into waterways, you can't get away from it.
On a few occasions, I've been privileged to play golf at a truly ultra-exclusive country club just outside Mexico City. You gain entry through two perimeters guarded by guys with submachine guns. The clubhouse is decorated with Aztec statuary and is lavish beyond belief, and the golf course itself is as manicured and meticulously landscaped as Augusta National. A mountain stream runs through the course, and comes into play on a half dozen holes. The water in the stream is literally gray, and bits of toilet paper are snagged on the rocks it runs over. The odor is like an Occupooper encampment. That's as pristine as it gets in Mexico, so nutcase nadin has a different frame of reference than decent and civilized Americans.
