Once a year, the collectors of antique tents in Germany get together for a rally. Last year, the organizers decided to hold it in Meinz. Unfortunately, the local burghers took a dim view of so great an influx of tourists ruining their turf with tent pegs. The citizens organized themselves so thoroughly that they even had an anthem: . . . “Let Old and Quaint Tents Be Forgot and Never Brought to Meinz!”
