There’s a scene in Cameron Crowe’s film “Singles” in which Campbell Scott pitches to Mayor Tom Skerritt the Supertrain: a high speed commuter train which he believes would solve Seattle’s horrendous traffic problems. The Mayor smiles and nods throughout the impassioned speech. But when Scott is done, Skerritt shuts him down in four words. He’d made up his mind before Scott even opened his mouth. This scene perfectly sums up Seattle’s perpetual transportation issue.
