just sticking my head in to put up a useful and cool map I found on wikipedia: map of U.S. ZIP codes.
Didya know that "ZIP" means "Zone Improvement Plan"? I guess the plan worked. Reading the article, I'm remembering dimly a time in grade school when we were taught to write and address letters and we wrote: "San Francisco, California" clearly, because otherwise the letter would go astray. That was before the two-capital-letter State designation came in (we had to learn those in school, too) and before ZIP codes were used universally. They were optional.
Not all good ideas or systems are adopted. I guess the good ideas that arise in conjunction with the power to implement them get adopted. Or perhaps, if there are people with the power to implement good ideas, who LISTEN to good ideas, then they get implemented. If not, George W. Bush, then you get stuck in a terrible, expensive war with no way out, and your economy crashes.
Okay, that was a stretch, but the election is ten days away. Are you voting?
