Take a drive or walk around your neighborhood, place of work or military station, and copy down any signs or advertisements that are incorrectly punctuated and post them. Photos or scans of the mistake are welcomed. (If you cannot locate any public grammar mistakes, identify a mistake that you tend to make or have made in the past.) Explain to the grammatically challenged, in one well-crafted and resourced/referenced paragraph, why grammar is important in today's society.
