MUNI and BART are two different worlds. MUNI is an unreliable bumpy ride through the third world of San Francisco, full of noise and color. BART is a clockwork shuttle silver bullet, careening silently through tunnels, carrying silent passengers to work, somewhere across the Bay. There are classes differences between the two, and age, and decible level. MUNI is a powderkeg scored by HipHop (though always lousy HipHop). Speaking of which, why is it you never hear b-boys bumpin' The Coup, or The Roots, or Tribe Called Quest, or Jurassic 5? Always gangsta shit, and not even the good stuff. I've always wanted to ride the bus with a boombox, play dub or tabla riffs, or Thievery Corporation. Dressed the way I do, looking the way I look, I simply can't pull it off. And why not? This is how it is on the bus, in the city.
