They should stop mentioning the Pam Am games. Nobody cares about the games. No terrorist is going to build a tunnel for the Pam Am games.
The only people who I hear mention the Pan Am Games are a) the media, and b) the politicians.
No one I personally know has expressed any sort of positive interest in the games, or have brought it up in conversation...other than the chaotic traffic nightmare it will cause.
I am thinking it's some homeless guy too.
These guys really must have needed some down time if they needed to build an actual cave...
