For the men's event, I happened to sit next to a group of Italians. Their cell phones were ringing all the time despite the sign outside that you were supposed to turn your mobile phones off before entering. For the women's event, Romania made a sweep and took all the medals. THe other half of their team was in the stands right behind me. THey would scream at the top of their lungs every time one of their teammates was up.
Security is pretty tight here.
It started when I was met going into customs at the airport by a female police officer. She guided me all the way through customs and baggage check where we were picked up by Olympic staff. The US and Israel are the only countries to have police security at the airport. Every time we enter the Olympic village we have to go through metal detectors and put our bags through X-Ray machines. I had to do the same when entering the gymnastics venue.
