Outside one of those places where we teahc our hcildren how to spell.
There are claims that the error has been there for months so I thought it would be worth hcecking.
Sure enough, here's a screen shot which I took directly from Google Maps. You can see it yourself if you search for Marta Valle High School at 145 Stanton Street, Manhattan, NY 10002.
I don't know how often Google updates the images but it certainly confirms that the error has been around for quite some time. There are leaves on the trees which suggests that the offending sign has been there since at least last summer, if not the summer before.
Anyway, just my twopennyworth but shouldn't that be X-ING rather than X-NG?
No one seems to have noticed that.
