I'm going to the games. Am I worried. Not very. The new greek government has brought in security experts from Israel, the USA, and NATO is also in a support role. The greek government is spending over 1 Billion dollars on security.
Having said that, I put in for opening ceremonies and didn't get them, and that's ok. If anything were to happen, that would probably be the event. I do have tickets to Men's Track and Field finals and Women's Gymnastics finals. I will only have to walk 5 minutes up the street to catch the Marathon runners.
I'm psyched!
