Eradicating incorrect punctuation, spelling mistakes and flawed grammar one sign at a time.
When I spot a grammar or spelling error in my own work, I fix it. When I spot a grammar or spelling error in other people’s work, I use it as a "what not to do" learning experience.
Some people, however, feel the need to stamp out all grammar, spelling and punctuation errors made by others. And according to this article, no signs are safe from self-proclaimed "grammar vigilantes", not even historic signs inside national landmarks.
In 2008, two Dartmouth College grads were arrested and charged when they took it upon themselves to fix punctuation errors on a historic hand-painted sign in Grand Canyon National Park.
The two were also prohibited from making any more corrections to public signs. So--for now-- the plaque in Red River College's Buhler Learning Commons is safe.
