I kept looking, posting details of my search to Twitter. Soon I had attracted a virtual army, ready to join the scavenger hunt. I had begun the year with 4,700 Twitter followers. By September I had more than 60,000 and climbing fast. I began hearing from celebrities and even a few personal heroes, offering their assistance out of the blue. The barbecue columnist for Texas Monthly — an idol to me, as a journalist and a native Texan — was watching videos of other people's parties taken at a Trump golf resort. He thought he'd spotted the painting in the background (he hadn't). Kathy Griffin, the actress, called me with her memories about visiting the set of Trump's The Celebrity Apprentice. Mark Cuban, the Dallas Mavericks owner, was sending me links on Twitter, new leads on Trump promises.
