There's nothing like sitting on the subway and seeing the following items:

• a man walks on with a dolly full of 3 large boxes...he parks it at the door and sits down at a seat not-so-close to the boxes. What do you do? "Excuse me good sir, due to the events of last week in London, I don't feel comfortable with you walking away from your stack of boxes."
• Across from the box man was a gentleman swinging a golf club back and forth in front of himself.
• Walking up and down the subway car was a homeless man singing a really sad rendition of Elvis' "Can't Help Falling In Love." It sounded like a over-played, warbled cassette tape.
• And during all of this, I'm reading an article in New York Magazine about how our subway systems are very venerable to an attack.
