Riding on a New York City bus recently, I glimpsed a going-out-of-business sign advertising discounts of “90% to 90%.” I couldn’t snap a photo of that gem from a moving vehicle, and when I returned the following day, the store was boarded up, denying me both the photo and the bargains within. But I did take a picture of another crime against arithmetic. (Yes, I know that I’m supposed to concentrate on grammar in this blog, but I can’t pass up illogical statements, even if they’re made with numbers.) This placard appeared on an uptown express bus, showing where the stops are:

Follow the numbers.

For non-New Yorkers, let me explain that most Manhattan streets are numbered. The city’s grid was established in the early 19th century by order of the City Council, which charged a committee with “laying out Streets… in such a manner as to unite regularity and order with the public convenience and benefit . . . .” What would that committee make of this sign, which sends a bus up north on First Avenue to 14th, 23rd, 34th, 29th, and 42nd Streets – in that order? And no, the bus doesn’t double back on 34th to hit 29th before making a U-turn and driving to 42nd Street.

This sign illustrates two truths, both “universally acknowledged”: (1) Proofreading is a lost art, for both letters and numbers and (2) To travel on public transport in NYC, you need sharp eyes and good luck.
