The BobboSphere: Don't believe everything you think.

­­­The Straight Talk Express is arguably the most famous bus in America right now. Riding around in the conveyance favored by everyday working class people is a nice touch really. It makes McCain seem like one of us. It's true that McCain now flies around in a Boeing 737 of the same name, equipped with first class seats for himself and his entourage, but it's the bus that people see and remember.

Buses remind us of going to work bleary-eyed in the morning crowded together with lots of strangers and then coming home exhausted at night crowded together in the same way. Buses are about enduring extreme heat and cold waiting for them to arrive. They are about the fear of being late to work when you miss one, or when it breaks down or gets stuck in traffic. They are about the fear of waiting for one at night in a dicey part of town, hoping that you won't become another mugging or rape statistic.

They stand over the city like the great predatory wading birds they are named after. And from time to time, like those great predatory wading birds, they come down swiftly on those below and take a life...often more than one. They are the construction cranes, whose numbers grew with the massive lending sprees that fueled the hi-rise building boom in our great cities.

But the construction cranes don't take lives with sharp beaks and unerring vision like their avian namesakes. Instead people get electrocuted when the cranes collide with power lines, operators fall out of them, they fall on top of people, or they crush people in the other gruesome ways that heavy complex machinery can destroy the human body.
