The other morning I saw an ad for the DC Metro system on the side of a bus that said, "House, Senate. Bus, Rail." I experienced a mini-flashback to the SATs and thought to myself, "That seems like an apt analogy--but why?"
Well: like the House, the bus system is the black-sheep sibling; it's less well-known, less predictable, and it has a lot more crazy people.
But is this possibly what Metro meant? Unlikely--why would they want to point out to bus riders that the strangers in whose armpits they are standing are probably wackjobs like Tom Tancredo?
But what else is it supposed to mean? That Metro is bicameral and that in order to get anything done you have to ride both a bus and a train? That once you get on the metro you'll be there for 6 years, while you'll only stay on the bus for 2?
It's a mystery. At least it will give me something to ponder while I ride the fickle, passionate branch of the legislature to work.
