If you saw unusual activity this morning at the Rio hotel-casino, there is no need to worry.
It was just training.
Las Vegas Fire & Rescue was practicing rescue techniques on the property's VooDoo Zip Line, which connects the 50-story Masquerade Tower to the Ipanema tower.
Such practice is not unusual because people do occasionally get stuck on the various thrill rides in Las Vegas.
A zip liner was stuck for several minutes in March of this year in Downtown Las Vegas. She was rescued by employees.
Two cousins from California were stuck on the Insanity ride on top of the Stratosphere Tower in 2005. They were stuck for approximately 2 hours before being safely resceued by employees.
