TIJUANA - This is my final post before signing off. I'm at the border separating the United States from Mexico. Over the past year, I've written 150,000 words and conversed with all of you through another 3 million or so. But standing here, at this border and at this moment, I'm at a loss for words.
Here is where video comes in handy. Watch men and women, young and old, interact with the U.S. across its border fence, and share what you're thinking.
And, finally, here are the many thank yous I owe to journalists, friends, and readers who made this project possible and worthwhile. Thank you for making this the most enlightening and exhilarating year of my life.
