I was merely responding to someone else who brought up a numbers-based argument only to find out that they... apparently don't have any.
The mere fact that people from Rhode Island now believe that they won't be able to successfully use the subway to attend a concert is I think pretty strong evidence that the story has gotten away from us a bit. Nobody here, least of all me, wishes to downplay your commute.
If I was to give a "gut" estimate for the overall deterioration of the subway service in recent years, though -- I'd peg it at closer to 30 or 40 percent than merely 20.
Now, look, that doesn’t mean it’s good that it’s declined so much, but context and perspective remain useful.
But compared to just about any major city in Europe... seriously, it's almost a joke.
