My first "visit" to Mexico occurred during my family's cross-country road trip in our motorhome, starting in Denver, driving out to California, and then back to NY. While we were in San Diego, we walked across the border into Mexico, walked about 100 yards, crossed the road on a foot bridge, and then walked back into the United States. It was quite exciting. OK, well maybe not. But at least I could say that I had been to Mexico.
