It is possible that texting originated in Tecate. Long before everybody over the age of two held an i-something in his hand, we had an effective communication system. About forty years ago the city government built a series of pedestrian bridges mainly for the purpose of extending the life-expectancy of its citizens. As you can easily see these corridors of safety are rarely used for their intended purpose but they brought effective social media to Tecate. What you see here is a lover texting his sweetheart, pleading forgiveness for his indiscretion and pledging eternal love. The system is not exactly secure. The whole town will know before noon. But the system is never down.
